I have a 16GB Jailbroken 3GS with ios 5.1.1. I wanted to sell it so I hit "erase all content and settings". It's now stucked on the circling logo for hours. How can I bring back the 5.1.1 and jailbreak it again? When I go to in iTunes>preferences>devices it shows that I have two backups of this phone, are they useful? Please kindly help me with a step by step guide. Thanks in advance.
