I am so confused. Two days ago, I plugged my iPad into my MacBook Pro. While it was syncing, I accidentally opened xCode while doing a Spotlight search for another application that begins with an "x". Some error message popped up in xCode, and I closed the application as I had opened it by mistake. Fast forward to today. I was playing with Gravitarium2 on my iPad, an app that responds to up to 10 fingers. I put 5 fingers on the screen and dragged them around and suddenly the multitasking bar came up. "What on earth? Is this a feature of the app?" I thought. I navigated over to settings, and sure enough, the multi-touch gestures setting was showing. How in the heck did this happen without applying ANY code/hacks to the device? They were just enabled by launching xCode for 15 seconds, if that. I'm not a registered developer, but I was at one time over a year ago with my iPhone 3GS. Which is why I have xCode on my MBP. I'm not upset, I just don't get it.
