    10 Dicas para seu iPad ou iPhone - Wall Street Journal



    Own an iPhone or iPad? Chances are there are some functions you're still not aware of. WSJ's Katherine Boehret has drawn up a list of 10 to help you get the most out of your devices.
    It's with you every moment of every day. It reminds you of little things that you sometimes forget, like calling friends on their birthdays and picking up the dry cleaning. It sleeps by your side, resting when you rest and working when you work. It even talks back once in a while. But how well do you really know your iPhone?
    After months of watching friends and family use their iPhones and iPads, I realized most of them were missing out on a lot of features. I'll walk you through 10 things you might not know your iPhone and iPad can do. Aficionados may know most of these, but typical users likely won't.
    1. Directly Access Apps
    If you're like most people, you have your iPhone set to show some pop-up notifications. They might show up on the home screen when you get a Facebook notification, or a text message, for instance, and even when the phone is locked and the screen is asleep. To open these messages, you don't have to first swipe to unlock your phone and then open the app. As long as your device isn't protected by a four-digit security code, swipe from left to right on the notification to open the app in which the message appeared. If you do use a code, you'll be prompted to enter it after swiping the notification.
    2. Tap to Scroll Up
    Give your pointer finger a rest from scrolling up, up, up to get back to the top of a page. Tap once on the status bar—where the time and battery life are displayed—at the top edge of the iPhone or iPad screen and you'll jump up to the top. This works for websites, email, Contacts and many other apps.
    Gary Hovland
    3. Keyboard Shortcuts
    Tapping on a glass keyboard has its downsides, but a few shortcuts could ease the experience. Tap and hold the "Compose new message" button in Mail to automatically bring up all your saved email drafts. And rather than switching to the number keyboard and then switching back to the letter keyboard, tap and hold the "123" key, then drag it to a number to select it. When you lift your finger from the number, the letter keyboard will appear again.
    When entering an email address, hold down the period key to see other address endings. Add emoticons to your keyboard by choosing: Settings, General, Keyboard, International Keyboards, Add New Keyboard, Emoji. When entering a Web address in the browser, hold down the .com key to see alternate URL endings, like .org and .edu.
    You can split the iPad's on-screen keyboard in two so you can grasp the iPad with two hands and type with your thumbs. This is on by default, though you might not know it. (To check, go to Settings, General, Keyboard and Split Keyboard.) To see the split keyboard anytime you're using the regular keyboard, spread your two thumbs from the center of the keyboard out. Or just tap and hold the keyboard icon (bottom right corner) and select Split. An Undock option also appears and this lets you move the keyboard up or down.
    4. Speed from App to App
    The iPhone and iPad have many apps running in the background. There are shortcuts for jumping around apps without going to the home screen. Double tap the Home button (a physical button below the screen) to see a pop-up tray of apps and swipe to the left to scroll through them. Select one to jump to it. On the iPad, do this is by placing four fingers on the screen and swiping all of them up at once. This and other multitask gestures are on by default on the iPad 2 and newest iPad. But you have to turn them on with the first-generation iPad by going to Settings, General, Multitask Gestures.
    5. Take Screenshots
    Ever see something on your iPhone or iPad screen and wish you could save that image, but can't figure out how? Press the Home button and the On/Off button (top right edge) simultaneously to take a screenshot of whatever you see on the device. You'll hear the same sound as when you take a picture with the Camera app. You can find all of your screenshots stored in Camera Roll, along with your photos, and share them via email or social networks as you do regular photos.
    Apple
    Splitting the iPad's on-screen keyboard in two lets you grasp the iPad with two hands and type with your thumbs. This is on by default—though you may not know it.
    6. Swipe to Search
    Another way to quickly find apps on an iPhone or iPad is to swipe left-to-right from the home screen. This reveals a search box in which you can type the name of any app to jump right to it. This search also finds contacts, emails, calendar items and texts, as well as other things.
    7. Read Websites More Easily
    Stop struggling to read overcrowded Web pages on the iPhone's small screen. Instead, tap the Reader button, found in the URL bar at the top of a Web page, and you'll see a much clearer, predominantly text version of the page. Even better: This view hides advertisements. It doesn't work with all websites. This also works on the iPad.
    8. A Smarter Camera (iPhone)
    If you've ever wished your iPhone camera had a physical shutter button, look no further. The phone's volume up (+) button doubles as a shutter button whenever the Camera app is opened. This hard button feels sturdier all around, plus it makes it a cinch to take self-portraits or to tell strangers how to take a photo of you and your friends.
    And speaking of handing your phone to strangers, don't forget about the lock-screen shortcut for opening the Camera: Slide up the camera icon (found at the bottom right of the home screen) to open Camera without unlocking the phone. You can do this with anyone's phone, regardless of whether or not you know their password because it only opens the Camera app, locking you out of all other apps—and other photos and videos—on the phone. Just the photos or videos you take at that moment will be visible to you.
    9. Digital Picture Frame (iPad)
    Put your iPad to work as a digital picture frame for a photo slide show. Tap the Picture Frame icon, which appears to the right of the slide-to-unlock bar on the lock screen.
    If you own an iPad case, flip it into its stand-up position, place the iPad on a table, press the Picture Frame icon and walk away. Guests in your home will have to unlock the iPad to access other apps.
    Photos can be pulled from all photos or specific albums, events or images of certain faces. Make these and other slide-show adjustments in Settings, Picture Frame.
    10. Mute or Screen Lock (iPad)
    The same button on the right edge of your iPad that locks the screen in portrait or landscape mode can double as a mute button. This comes in handy if you find yourself frequently muting the iPad. Change this button's default lock function by going into Settings, General, Use side switch to: Lock Rotation or Mute. By default, this button is on Lock Rotation. Another quick way to mute is by pulling up the multitask bar by double tapping Home (or using a four-finger swipe up), then swiping left-to-right to see a mute, as well as sliders for volume and screen brightness.

    iPads: economicos em energia, e na fatura da eletricidade (talvez nao no Brasil)

    Pelo menos nos EUA, os iPads custam pouco e gastam muito pouca energia.
    No Brasil, a fatura é sempre mais cara...

    It costs just $1.36 to charge an iPad for a year
    NEW YORK (AP) — That coffee you're drinking while gazing at your iPad? It cost more than all the electricity needed to run those games, emails, videos and news stories for a year.
    The annual cost to charge an iPad is just $1.36, according to the Electric Power Research Institute, a non-profit research and development group funded by electric utilities.
    By comparison, a 60-watt compact fluorescent bulb costs $1.61, a desktop PC adds up to $28.21 and a refrigerator runs you $65.72.
    The group, known as EPRI, studied the power consumption of Apple Inc.'s iPad to determine the effect that the newly-popular devices might have on the nation's electricity use.
    The answer: not much.
    If the number of iPads triples from the current 67 million, they would need the electricity from one small power plant operating at full strength.
    But if people are using iPads instead of televisions to play video games, or ditching their desktop computers for iPads, the shift to tablets could mean lower overall power consumption. A desktop computer uses 20 times more power than an iPad.
    Baskar Vairmohan, the EPRI researcher who conducted the iPad test, said the group is now studying usage to understand whether the explosion of tablets is adding to power consumption, or reducing it.
    Residential power demand is on track to fall for the third straight year, according to the government. A weak economy is keeping people in smaller houses and shacked up with others. At the same time, efficiency programs are pushing more efficient light bulbs, air conditioners and other devices into homes. Refrigerators use a quarter of the power they used a generation ago, according to EPRI.
    For the iPad test, Vairmohan measured the amount of power used to charge up an iPad with a drained battery. He assumed that users would charge up every other day. Over a year, the latest version of the iPad consumed 11.86 kilowatt-hours of electricity. (Older versions consume somewhat less power.)
    The juice would cost $1.36 at the U.S. average residential price of 11.49 cents per kilowatt-hour.
    But there's an even cheaper way to go than the iPad. EPRI calculated the cost of power needed to fuel an iPhone 4 for year: just 38 cents.

    Como ficar rico sem muito esforco: trade marks

    Você não precisa ser um gênio, um grande inventor, nem ter o gênio da lâmpada ao seu lado, ou uma brilhante equipe de engenheiros e cientistas de laboratório, para descobrir uma nova maneira de tornar fácil o que é atualmente difícil.
    Basta ter um pouco de imaginação, ou esperteza, e registrar nomes fantasia, ou marcas de comércio, junto a escritórios de propriedade intelectual, e depois negociar ou vender o seu título de propriedade para grandes empresas que necessitam desses nomes para comercializar seus produtos.
    Tal como ocorreu no caso abaixo, sem que sequer saibamos se os "expertos" jamais estariam no mercado real de produção de suas marcas registradas. 
    Durante certo tempo, não sei se continua, firmas paraguaias eram especialistas em registrar nomes de produtos brasileiros no escritório local de patentes, barrando, portanto, o acesso do mercado paraguaio à oferta dos sócios do bloco do Mercosul. Talvez o caso tenha sido resolvido, mas o fato é que paraguaios espertos ficaram ricos nesse jogo.

    Apple 'settles China iPad trademark dispute for $60m'

    A consumer using iPadSome critics have accused Proview of trying to cash in on the success of the iPad

    Related Stories

    Apple has agreed to pay $60m (£38m) to Chinese firm Proview to settle a dispute involving rights to the "iPad" name, a court in China has said.
    Proview had claimed that it owned the rights to the iPad name in the Chinese market after registering it in 2000.
    However, Apple had insisted that it had acquired the worldwide rights for the name in 2009.
    A court in Guangdong had asked the two firms to try to reach a settlement.
    "The iPad dispute resolution is ended," the Guangdong High People's Court said in a statement.
    "Apple Inc. has transferred $60m to the account of the Guangdong High Court as requested in the mediation letter."

    When Apple is on the receiving end of a litigation, especially in China, it is a sensible move for them to settle it and move on”
    Andrew MilroyFrost & Sullivan
    Apple had bought the global rights to the "iPad" from Proview's Taiwanese affiliate for $55,000 (£35,000).
    However, the Chinese firm had argued that its affiliate did not have the rights to sell the iPad name rights for China, which is one of the fastest-growing markets for Apple's products.
    The dispute between the two firms resulted in Apple's iPads being pulled off the shelves in some parts of China.
    Proview had even sought a ban on the sales of the product in Shanghai as part of the dispute, a move that was rejected by the courts.
    After the court announced the settlement on Monday, Proview confirmed to the BBC that the firm had agreed to the settlement.
    "The case is settled, both sides are satisfied with the agreement," Ma Dongxiao, a lawyer from Shenzhen Grandall Law Firm, which is handling Proview's case told the BBC.
    Sensible move
    China is one of the biggest markets for Apple's products and demand for its gadgets has been increasing steadily in the country.
    However, it is starting to face increasing competition from rivals such as Samsung as they look to tap into the lucrative Chinese market.
    Analysts said that one of the key reasons behind Apple agreeing to settle the naming dispute is that firm may not have wanted its sales in the country to be disrupted and as a result lose some of its market share to competitors.
    "When Apple is on the receiving end of a litigation, especially in China, it is a sensible move for them to settle it and move on," Andrew Milroy of Frost & Sullivan told the BBC.
    "That would help minimise the disruption to the Apple juggernaut."
    End of the road?
    The dispute between the two firms over the rights to "iPad" name was not limited to China.
    Essex streetProview claimed Apple set up a special company in Roydon, Essex to acquire the rights to iPad name
    Proview had also lodged a case against Apple in the US.
    It had accused Apple of deceiving it into selling the rights to the name by setting up a company, IP Application Development Ltd (IPADL) in the UK.
    It claimed that Apple said the trademark was "an abbreviation for the company name".
    However, that case was dismissed by the court earlier this year.
    Analysts said that with the two firms agreeing to a settlement in China, it was unlikely that Proview would take any further action against Apple.

    Apple: sempre renovando os sistemas...

    Je suis preneur, como diriam os franceses...
    (desculpem a inserção publicitária, mas se trata apenas de um registro).


    Apple annonce IOS 6, avec Google en ligne de mire

    Le Monde.fr | 

    La première keynote de la WWDC (World Wide Developper Conference) sans Steve Jobs, qui s'est tenue lundi 11 à San Francisco, n'a pas réservé de grande surprise, comme aurait pu le faire un nouveau modèle de son iconique iPhone. Tim Cook, qui officiait à la place du charismatique patron de la firme à la pomme, s'est tout d'abord félicité du succès de l'App Store qui permet de télécharger des programmes sur soniPhone ou son iPad. Plus de 400 millions de comptes ont été ouverts avec des cartes de crédit et 30 milliards d'applications ont été téléchargées, selon l'entreprise.

    Comme prévu, Apple a annoncé le renouvellement de sa gamme d'ordinateurs, dont les processeurs seront plus rapides et la mémoire plus étendue. Le fabricant a également présenté un ordinateur portable doté d'un écran à la résolution record (2880 X 1800 pixels), avec une mémoire, un processeur et une batterie dopés. Cet appareil sera enfin équipé d'une prise HDMI, pour le relier à une télévision par exemple. Tout cela avec une épaisseur inférieure à celle d'un doigt. Le prix sera élevé : le modèle le plus puissant sera vendu 3 700 dollars.
    Avec ce nouveau produit, Apple espère continuer à séduire d'anciens utilisateurs de PC. Plus de 66 millions de machines fonctionnent désormais sur son système d'exploitation Mac OS X, trois fois plus qu'il y a trois ans. Et les consommateurs adoptent rapidement ses nouvelles versions. Plus de 40 % d'entre eux ont acheté la dernière en 9 mois - il a fallu 27 mois pour que Windows 7 atteigne ce niveau, a souligné Apple.
    OFFENSIVE CONTRE ANDROID ET GOOGLE
    L'entreprise californienne a dévoilé la nouvelle mouture de son système d'exploitation, baptisée "Montain Lion", qui sera disponible le mois prochain pour 19,99 dollars. Elle propose une synchronisation améliorée avec iCloud : calendrier, documents, notes, listes de choses à se rappeler et les conversations via des messages avec ses amis que l'on peut enrichir de photos ou de vidéos. Un centre de notifications permet de regrouper tous les messages qui apparaissent sur l'écran. Le système intègre aussi la reconnaissance vocale et une nouvelle version de Safari, le navigateur d'Apple, et la fonction air play pour visionner l'écran de son ordinateur sur sa télé.
    La physionomie de Lion se rapproche d'iOs, le système d'exploitation destiné aux appareils mobiles de la marque (tablettes et smartphones). Plus de 365 millions d'iPad, iPhone ou iPod touch ont été vendus depuis leur lancement, et les trois quarts utilisent la dernière version d'IOS. "Ce qui est loin d'être le cas pour les machines fonctionnant sur Android", s'est amusé à souligner Tim Cook. Selon Apple, 47 % des photos échangées sur Twitter proviennent de machines iOS, qui compterait 75 % d'utilisateurs satisfaits, contre moins de la moitié pour les utilisateurs d'Android de Google, a affirmé Apple.
    La firme a dévoilé la nouvelle version d'IOs, IOs 6, qui offre 200 améliorations dont une meilleure intégration de Facebook et de Siri. Le système de reconnaissance vocale sera proposée dans de nouveaux langages dont le coréen, l'espagnol et le chinois. Siri fonctionnera aussi sur la dernière version de l'iPad. IOs 6 offrira aussi une nouvelle version de Map, l'application de cartographie avec GPS intégré. Il abandonne celle qui était fournie jusqu'à présent par Google, plus que jamais son principal concurrent sur mobiles et tablettes.

    Mac Addicts (como eu): calma com o novo iPad...

    Melhor não sair correndo, imediatamente, melhor não sair correndo nunca.
    As coisas sempre melhoram na segunda ou terceira versão...

    The new iPad: 5 reasons to buy, 5 reasons not to

    Robert Galbraith/Reuters - Apple's senior vice president of worldwide marketing, Phil Schiller, speaks about the icons for new features; the retina display, quad core chip, a new camera with face detection, HD video, Siri and 4G LTE service for the new iPad during an Apple event in San Francisco.
    Every device has its pros and cons. Here are five reasons to buy — and not to buy — the latest iPad.
    Reasons to buy:
    Gallery
    Gallery
    1. The display: If you’re really into photos or video, then the screen is probably the single-most compelling reason to upgrade. Apple says that the iPad screen has more pixels than an HDTV.
    2. Dictation: There hasn’t been much attention paid to this little feature, probably because everyone was bummed that Siri wasn’t in the new iPad. But dictation will go far on the iPad, as many people find typing on the tablet a total pain.
    3. LTE: Faster Internet access means faster video streaming — which will be a joy to watch on the iPad’s new screen. It will also likely increase productivity on the iPad, because users will almost always be connected to a very fast network.
    4. App store: This is really more a reason to buy Apple than specifically to buy this new tablet, but the fact of the matter is that the App Store has some of the best tablet apps out there — more than any other tablet app store.
    5. Video/photo editing: This iPad might not be enough to finally persuade you to get rid of your computer, but this version of the iPad is creeping up. Before, it was kind of pain to edit photos and video that you took on your tablet and then share them from the tablet. Now, with an upgraded version of iMovie and a new iPhoto app, it’s much easier to do some quick work. Although the apps won’t be able to handle really complex editing, it’s welcome news for more the more serious amateurs who just want their stuff to look good.
    And not:
    1. LTE: Yes, I know I just listed this as a reason you should buy the new iPad, but it comes at a premium that might not be worth it for everyone. Adding LTE adds $130 to the price of any iPad model, plus the expense of the data plan.
    And if you will do most of your non-WiFi iPad work somewhere without great LTE coverage, you’ll be roaming on the 3G network that already powers the iPad 2.
    2. Competitors: Amazon is rumored to be coming out with a 10-inch version of the Kindle Fire. Microsoft is making a push with Windows 8. Even Google is expected to come out with a pure Android tablet.
    3. Is it the size you want?: The iPad’s screen size — 9.7 inches — isn’t for everyone. The tablet is portable, but if you want to hold it one-handed for any length of time, if can be tiring for your hand muscles. That means commuters who often find themselves with standing-room-only might not find it completely ideal.
    4. No SD card: The iPad comes in three memory sizes: 16 GB, 32 GB and 64 GB. And it seems like that’s going to be the case for a while. Other tablets offer users the option of expandable memory through an SD card or even the option of a USB port, but that’s not the case with the iPad. So if you want expandable memory, you’re better off with another tablet.
    5. You own an iPad 2: The eternal agony of the upgrade cycle might have you completely paralyzed with the decision to buy or not to buy right now. But if you’re happy with your iPad 2, there’s really no reason to rush out and get the new version of Apple’s tablet today.
