Here's what it's doing (and not doing): Tonight I was listening to some music, and the screen dimmed, kind of shimmered and the phone died. I noticed the back was very warm. After a while I was able to reboot it, and it came up for about a minute and died again. Got hot again on the back. I let it sit for a while and it finally came back up again. I tried synching it with my laptop, but it won't see the phone. As a matter of fact, even when plugged in to a charger, the phone doesn't see it. Won't charge. Tried multiple cables, still nada. The phone continues to die, then will come back. Then gets hot and dies. Oh, another thing, I can't get it out of headphone mode. If I have headphones plugged in, I get sound. Unplug them and it still is in headphone mode. I tried going into DFU mode and it won't. Right now the phone is off, but is very warm. Won't boot at all. I tried the power button and home button for 10-15 seconds, nothing. Any ideas would be great, otherwise I'm off to the AT&T store tomorrow. BTW, the phone isn't jail broken, and it's whatever firmware is most current right now. Thanks for reading my ramblings!
