A long time ago, we saw some awesome multitouch gestures coming to iOS 4.3 thru one of the developer builds of the software. We were very excited about the idea of not having that loud Home Button click wake the wife while switching apps on the iPad. Then it disappeared before release (damn you, Apple).
Now you can have those features. AWESOME! But…it's going to cost you five bucks. Sorry.
Still, if interested in multitouch, and buying Xcode 4 from the Mac App Store (that's where the $5 comes in) then you, too, can have iPad multitouch gestures. We're not into the idea of paying for something we think should have come free, but developers may have a use for Xcode anyway. You can buy it here.
Once you install Xcode, you will have to launch the software and connect your iPad or iPad 2 to your computer:
1) After connecting your iPad, it should appear on the Xcode devices list.
2) Click "Use for Development"
3) You will be asked for your iOS developer information. Screw that. Just click cancel and ignore the error message.
4) Wait for developer mode activation to complete and then go to your iPad general preferences. From here, turn Multitasking Gestures to "ON"
Now you have the cool swipes and app closing and switching at your fingertips. No pressing of the Home Button required.
Perhaps it will finally be added when Apple updates iOS again. We aren't sure why they didn't just leave it in in the first place, as it seemed very cool.
