Ok seems like there are still some problems with a few from viewing this forum. There are several reason for failing but the most that i have helped through e-mail are just not following the steps properly or they have the wrong firmware. I am now on iPhone #74 JB/Unlock... 2 and 3g versions with no issues. I am using Windows Vista, Clean install of iTunes 7.7 (used revosetup to WIPE the old iTunes). All but about 10 2G phones have been on 1.1.4 with Ziphone used to JB and unlock. The 3G phones I have done (approx 8 of them) I had some issues with entering DFU mode but persistance paid off.... No trick just kept trying...
