Can you give us some more info was it JBen? why did you reboot it? did it reboot, freeze? Try open iTunes hold down the home button on your phone and plug in the USB plug keep holding the home button until you see the USB cable to the Globe, DFU mode. You can also try pluggin in the phone for a couple hours in the wall to make sure it is charged up then try powering on?

It was jailbroken. I rebooted it, like I always do, after I get out of class. It didn't really turn on at all, the apple logo came up and it just shut off.

That's not DFU that is recovery mode, DFU will have a completely blank screen, I was hoping someone had figured out this without a restore, this happened to me this morning ater attempting the upgrade in cydia. I don't have a current back up...this blows.
