Cool, I didn't see that post (and I still haven't updated to Beta 3 yet). Thanks for the info! Hopefully that isn't annoying.
The only downside I can think of is playing a full-screen game that has on-screen control pads (Street Fighter 4, NBA Jam, for example)... I'm wondering if those will cause the notification center to accidentally be accessed. That would be terrible! I can't test this though since I'm still running iOS 4 on my iPhone, I only put iOS 5 on my iPad but don't have those games on it.
Anyone have any experience with something like this?
