So I've had my jailbroken iPhone 3Gs since August last year and never had any problems with it, until yesterday. It froze so i try re-booting it (with the unlock and hold button) and it starts rebooting and the silver Apple icon appears, but then a spinning will appears on top of it, then freezes for about 4 minutes and starts over! I'ts been on this constant cycle for about 15 hours now. I've tried connecting it to 5 different computers with iTunes and non of them will recognize it, so I can't restore. I've also tried to put ot into DFU, again with no success. I would take it to support but don't know if they can actually do something to you if you have a jailbroken iPhone (like fine you, etc). Pls help?
