    Hi, i have tried following all your procedures and in the end manage to get it to the homepage of the iphone. however, the phone is unable to identify wifi, bluetooth and also modem firm ware. for both wifi and bluetooth it is highlighted in grey and for modem firmware, it has no descreption whatsoever there.
    Please advice on this matter.
    My phone is a 3gs, ios 5.0.1. i previously tried unlocking it with redsnow and upgrading the baseband to 06.15.00 (ipad baseband). my serial number is 87144******

    hello iphoneinformant. i followed your directions to the tee as well. only thing different is that ibooty wasnt created on my desktop. i got the phone to the point where the apple logo shows with the bar under, but from there the bar would fully complete. then in itunes it would ask to register, i would register as new… then it would install the firmware and be read on itunes and the phone would reboot. now  itunes says its syncing, while the phone is stuck in the circular loading screen. any suggestions??

    Hello IphoneInformant, great video. i followed you direction to the tee, but i still get no service env after i put ultrasnow. When ultrasnow was installing i did get a message “Could not activate cellular data network” please help I did toggle the airplane mode too, still no luck. I have a iphone 3gs, running 5.0.1 (custom ipsw created by snowbreeze) and the base band is 6.15.00.

      It seems that there is a bug with ultrasn0w working on 5.0.1 I too have encountered this problem. I will be working on a fix and will let you know.
