So I just spent 12 hours unblocking my iP4 after JBing it. It was a successful JB but after installing BBSettings or maybe a bad repro my phone got bricked. I tried EVERYTHING from PwnageTool, Tiny Umbrella, custom IPSWs, default IPSWs, Recover Mode, DFU, blah blah blah. NOTHING worked. I got all the errors while trying to restore from IPSWs. Errors 1, 11, 1015, 1604 etc. Finally I edited my hosts file to Code: #127.0.0.1 gs.apple.com You need the hash sign (#). This also applies to the second to last line. Code: #22.214.171.124 gs.apple.com I was finally able to restore from my backup from yesterday and everything is good as new. If you don't know how to edit your hosts file use this link as it's easy and correct. I originally JB only for TetherMe but got carried away with other junk JB apps and tweaks. I highly recommend you only use what you really need for JBing and stay away from as many tweaks and 'hack' repos as you can. .
