I have an iPhone 4 16gb black that is currently JBen on 5.1.1 with saved SHSH blobs on Cydia. It also has a mushy power button - works only if mash it down and only some of the time. The plan was to sell it on eBay (with full disclosure of the power button issue). I submitted for an ATT unlock but have to restore the device to do that. I tried restoring to vanilla 5.1.1 but no-go... Downloaded Redsnow, retrieved my SHSH blobs and stitched them. When I tried Pwned DFU mode, I got some error (late last night, can't recall) and had to do a reset with power/home x 10 seconds. I was going to try again but am worried that the power button only has so many presses left in it and I may end up 'bricked' if I can do the home/power reset if DFU fails again... Questions: Will doing a restore with a modded/PWNed ipsw work for a factory unlock? Any suggestions on above? If I do the DFU ipsw with Redsnow do I use Vanilla ipsw, one with stitched blob?? Thanks!
