I just tried jailbreaking my 3g 16gig iphone running on 3.1.2 using blackra1n and got through to the restore screen on the phone but never got to see the blackra1n screen. My pc then proceeded to tell me that the phone was jailbroken and that it was waiting to reboot, which it never did. I'm running a pc thats running on XP, tried restoring to my back up and tried to jailbreak again with no luck. Anyone have any suggestions on what might be causing the problem. Each time i try to run blackra1n it's telling me that my phone was successfully jailbroken but no icon on the phone. Thanks in advance for any responses and help.
