I just upgraded my iPod Touch 2G to firmware 3.1.2 from 2. something. First thing I do, of course, is Jailbreak it. Everything went fine and it was all good. But for some reason I couldn't get the themes to work, and iPhone Browser wasn't recognizing my Jailbroken iPod. So I tried respringing, didn't work. So I turned the power off. When I tried to turn the power back on, the Apple logo shows up, but after ~10 seconds it goes black. Doesn't turn on at all. I figured it was out of batteries, but when I plug it in my computer doesn't recognize it. I've tried to restore it by holding down the Home and Sleep button but it didn't work. DFU didn't work either. Since my 1G broke and I bought this 2G over the summer it should still be under warranty. But with it Jailbroken and all I don't want to have to take it into the Apple Store. Anything I can do? Thanks in advance.
