So I noticed my iphone has been rebooting within the last few days. It would go from a full charge before reboot to showing me an empty battery after. Now it just sits there at the apple logo and then shuts off. I have it jailbroken with 3.1.2 firmware on blackrain. Is there a way to get it to boot without a restore? Is there even a 3.1.3 jailbreak for the 3g out yet?
