So I've been trying for weeks now to find a solution on how to rejailbreak my iphone 4. I jailbroke it on 4.2.6 back in February and had some problems so I restored it. I went to jailbreak it with PWNage tools and followed to steps to create the IPSW and tried to restore w iTunes with that IPSW. The phone successfully installed it, or so I thought, and when the phone restarted it was stuck on the apple logo. I let it sit and sit, but nothing happened. I had to put it back in DFU mode and restore back to 4.2.8. Anyone have a solution to this? I don't have a PC so that is not a solution. Thanks!
