It worked for me..!!! I have 3gs - couple of months ago upgraded to BB 6.15 to do manual unlock/jailbreak.. Afterward AT&T started accepting unlock request and my request was granted. I wanted to do official unlock but after doing backup/restore with itune for 6.0.1 my phone was waiting for activation. It always give me message insert SIM card. I figured out that it was not able to understand SIM. Took it to at&t/apple - noone helped. At last I found this article and downgraded BB and what next... It worked great..it finished unlock process from apple and now my iphone is officially unlocked.. Thans very much to iclarified.com...!!!

wow this actually worked! i had a 3gs iPad baseband completely bricked and constantly rebooting every 5 to 10 mnts, and wifi and bluetooth blank and when going on settings the firmware was blank as well, i stopped trying a couple of months ago due to multiple tries but no luck, long story short i noticed this was out, i tried it TWICE and it worked!!!! i think you gotta try it twice because in order for the downgrade to work there has to be a firmware showing on the about section in the settings, so when doing it the first time it flashes it and the second time it fixes it and downgrades..... thank u muscleNerd!!!!! good luck everyone!
