[foreveraudio]

i got a 3gs here , guy says it was on 4.1 and unlocked he did a restore and now its at connect to itunes screen,
iv tried doing a custom restore with 4.2.1 with the 6.15 bb with snobreeze and no luck and iv tried 4.1 custom with no luck

i even tried restoring factory to 4.3.5 but end up with 1015 error which tinyumbrella kicks it out only to bring it back to the connect to itunes screen i dont know what else to try and help will be great, thanks all
