Your new iPad 2 might not be as full-featured (or as complicated) as a laptop or desktop PC, but a few neat tricks are still hidden between the surface. Read on to learn how to secure your iPad, sync your bookmarks, and more.

1. 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.

2. 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.

3. Multitask in iOS: You probably already know that you can press the Home 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.

4. 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.

5. 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.

6. 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.

7. 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.

8. Tweak AutoFill: You can choose to enable Safari’s AutoFill feature in Settings, 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.

9. 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.

10. 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.
