I have jailbroken iPhone 3gs, with 5.0 and 5.13.04 baseband. After upgrading cydia and installous, phone tried to reboot. But won't move past frozen spinning wheel. I have old bootrom. Can I restore back to 4.1 and jailbreak again?? I tried redsnow to reboot but pineapple comes on and after 3 to 5 min same spinning wheel. Please help. If I force it off after redsnow reboot and try to turn it on I get apple logo then frozen wheel.
