it seems lately there have been a lot of 3gs dying. Add me to the list. I was in an app and battery died so I put it into car charger and it didn't charge. I went home and plugged USB into pc (windows vista) and it didn't charge. Now I was starting to worry because I wasn't even getting a dead battery screen, just black. I tried different usb cords and no luck there. I tested each with my ipod touch and they worked fine for that. PC couldn't recognize my dead phone, I tried hard-resetting and going into DFU with no luck. I went out and bought a new wall charger and still no luck! Anything I'm forgetting???? It is jailbroken running 3.1.3.
