iOS 4.3 was released not too long ago, and I for one was disappointed to find that multitouch gestures were not enabled. I suppose Apple and developers still have some testing to do before these features are enabled. Either way, here is a quick how-to, showing you how to enable them on your iPad or iPad 2 running iOS 4.3. (No Jailbreak or hacking required!)
One thing I should mention before we get started is that, you will need Xcode 4 from the Apple App Store for this to work. Xcode will run you $4.99.
Step 1 Download and install Xcode. Xcode is 4+ GBs, so the download might take a little while.
Step 2. Once Xcode is installed, launch xcode, connect your iPad and wait for your device to appear in your Xcode devices list.
Step 5 Wait for developer mode activate and then go to your iPad general preferences to make sure that Multitasking Gestures are set to “ON”.
Step 6, Enjoy!
