I had an old jailbroken 3gs lying around and decided to reset it to factory settings via the settings in IOS. I didn't know that bricks the phone if you're on a jailbreak. I've done all my research regarding the matter. I've tried putting the phone into recovery mode and restoring via itunes but itunes says it can't contact the software update server. I've tried using redsnow to restore it to an IPSW file but redsnow says that version of the IPSW file is not supported. I've hit rock bottom now and ask any iphone/ios gurus for help.
