Caution if you are jailbreaked your iPad. My iPad was in infinity boot loop. I have to restore it from, I guess I will not jailbreak it again.
I wasn't sure what caused the infinity boot loop, all I did was showing up a photo to a friend and then i put the iPad. And then it went on infinity boot loop.
I had that happen to me also. I was worried at first, but good thing I read. Lol. All I did was hold the power button and home screen button for at least 10 secs. Or until it reboots to the apple logo again. Everything good after that. I'm still jail broke, nothing lost, didnt have to restore. iPad working good. My iPad is 32 gb wifi ver. 3.2.1. I got full force, mxtubedownloader, sb settings, winter board( which is very cool because it let u change the UI appearance, like icons,
Themes, etc..), ifile, quake 3, bt mouse stack, backgrounder, curtiuos, adownloader. Have to look hard for the iPad only or iPad compatible apps.
So if u get the infinity loop, try what I did first. I had that happen twice n worked. Most of the time it occurs from restarting springboard after app or extension finishes loading.
