Ipad 2 is one of the most popular gadgets ever made, although not as powerful as main stream desktops or laptops but they can be used well do more than the basic stuff. Here today we will list some useful functions and tricks of Ipad2.
Download the free iPad User's Guide: You may have noticed that your iPad didn't come with a big printed manual--that's not Apple's style. However, you can download the PDF version of the iPad User's Guide from Apple's Web site, or you can read it in iBooks if you have that installed (iBooks is available as a free download in the App Store). Make sure to download the manual for iOS 4.3.
Use the Side Switch: You can use that neat switch on the side either to enable and disable audio alerts (this doesn't affect video/audio playback) or to lock the screen's orientation in portrait or landscape mode. You can toggle which function is assigned to the side switch by opening Settings from the Home screen, selecting General, and choosing the function you want under the 'Use Side Switch to' heading.
Common Keyboard Shortcuts: Here are some great keyboard shortcuts you can use:
Command-C, X, and V for Copy, Cut and Paste
Command-Shift-Arrow key-based text selection
Option-key shortcuts for typing diacritical characters
Command-Z and Shift-Command-Z for Undo and Redo
Multitask in iOS: You probably already know that you can press theHome button twice to bring up a list of currently running or suspended apps. However, you can also swipe the multitasking bar left to right to quickly access audio/video playback controls, a shortcut to the iTunes app itself, and volume controls. Also, when you choose whether the Side Switch should mute alert sounds or lock the screen orientation (see the item above), the function you didn't choose will appear in this shortcut bar.
Application Exit: If you press the Home button by mistake in an app so that you’re forced to quit this app, there is a useful method for you to avoid application exit. Just keep holding down on the Home button without letting go of it. It means to tell the iPad that you really didn’t want to close down that app.
Speed up your sentences: Double-tapping the spacebar while typing a message will type a period and then a space.
Don't let AutoCorrect mess you up: If you don't like the option AutoCorrect gives you, reject it by finishing the word as you prefer, and then tapping the suggestion. If you want to use AutoCorrect's choice, just type a space or punctuation mark, or tap Return, the moment it pops up.
Secure your backups: You can encrypt your iPad's backup data in iTunes. Just open the iPad in iTunes, click the Summary tab, and check Encrypt iPad backup under the Options heading.
Prevent automatic sync once: Sometimes you don't want to sync your iPad when you connect it to your computer. In this case, hold down Shift-Control (or Command-Option, on a Mac) in iTunes while plugging your iPad in, and iTunes will skip the automatic sync just once. Alternatively, you can safely interrupt a sync by dragging the unlock slider while the iPad is midsync.
Toggle data roaming: If you're using a 3G iPad, you can turn data roaming on in the Settings, Cellular Data menu in case you want to try receiving cellular Internet through a different provider (fees may apply). You can also check your data usage by going to Settings, General, Usage.
Make your passcode more complicated: iOS defaults to a four-number passcode, but you can turn it off by going to Settings, General, Passcode Lock, Simple Passcode. Now you can use any full keyboard password to lock the iPad. The password also helps to encrypt your mail and attachments on the iPad, so you probably want to make it safer than a four-digit number.
Set the iPad to self-destruct in 10 seconds: Okay, not really--but you can set the iPad to erase all data after ten failed passcode entry attempts by checking the Erase Data option under Settings, General, Passcode Lock.
Tweak AutoFill: You can choose to enable Safari's AutoFill feature inSettings, Safari, AutoFill. From there, you can tell Safari to fill forms automatically either by using your specified contact information or by remembering the names and passwords you've entered while logging in to Websites in the past.
Sync your bookmarks: You can use iTunes to sync your iPad's Safari bookmarks with your PC's Web browser. Open the iPad tab in iTunes, click the Info tab, scroll down to the Other heading, check Sync bookmarks with, and choose your preferred browser.
E-mail photos: The easiest way to e-mail photos from an iPad is to open the Photos app, select a photo, press the button in the upper-right corner (the rectangle with the arrow, not the trash button), and choose Email photo... to send.
Choose an app for e-mail attachments: You can open a file attached to an e-mail message by tapping the attachment in Mail, but if the default app isn't the one you want to use, you can press and hold and wait for a menu that lets you select an app.
Use the iPad as a picture frame: Not for physical photographs, silly. You can press the Picture icon in the lower-right corner of the Lock screen to have the iPad display its available photos.
Show traffic conditions: Open Maps, press the dog-eared page icon in the lower right, and then turn the Traffic overlay on. If your iPad has an Internet connection, Maps will show real-time traffic conditions in the displayed area. Green means traffic is going at the posted speed limit, yellow means traffic is slower than the posted speed limit, and red means traffic is stop-and-go.
Share podcasts with friends: Listening to a podcast that you think a friend would like? You can share the link while you're listening to it by pressing the Email button while it's open.
Don't forget your downloads: You can immediately see if your iTunes account is due for any incoming downloads by opening iTunes on your PC, clicking the Store menu, and selecting Check for available downloads. This trick can come in handy if your download process is interrupted, or if you missed some bonus iTunes content that came with an album you purchased.
Turn on Universal Access: You can enable options such as closed-captioned movies, VoiceOver screen reading, zoom magnification, and inverted white-on-black text by selecting the iPad in iTunes, opening the Summary tab, and clicking Configure Universal Access under the Options heading.
Specify your Spotlight searches: The iPad uses Spotlight for its built-in search functions, and you can tweak it to your needs in Settings, General, Spotlight Search. If you have a lot of data on your iPad, for example, you can selectively disable search in different categories (Contacts, Applications, Audiobooks, Notes, Events, Mail, and so on) that you don't use so that your desired results show up faster. You can also simply change the order in which the search-result categories display by dragging them up and down, so that your more frequently used search categories show up at the top of the page.
Turn off in-app purchases: Go to Settings, General, Restrictions and tap Enable Restrictions to selectively enable restrictions that apply to your apps, content, Game Center, and more. If you're worried about other people breaking your bank account on in-app purchases, just disable In-App Purchases under the 'Allowed Content' setting.
Switch up the fetching frequency: Your iPad automatically grabs new data, such as incoming e-mail. However, the iPad periodically activates apps that don't support iOS's Push feature so that they can go "Fetch" new data--which uses the tablet's battery life. You can tweak your Push and Fetch settings in Settings, Mail, Contacts, Calendars, Fetch New Data.
Change your e-mail signature: Don't be one of those people who leave the default 'Sent from my iPad' signature on all their messages. Change it in Settings, Mail, Contacts, Calendars, Signature to...well, anything but that.
Swap the search engine: Too good for Google? You can change Safari's default search engine by going to Settings, Safari, Search Engine. Alas, you can only choose from Google, Bing, or Yahoo--no bringing back AltaVista for you.
Take a screenshot of whatever is on the screen: Press Home and the sleep/wake button simultaneously. The screenshot will automatically appear among your photos.
