Okay, but still it's a second hand iphone, and that i don't have any at&t account, will i not need the guy that sold me the iphone do it for me ? (because I've seen on the internet that to be elligible, you need to have all your bills paid... but i never paid any bills to at&t... so... I guess that i will need the guy that sold me the iphone to do it for me...
I have another question. I tried to jailbreak my iphone and it failed. The springboard loading loop is frozen at the start up... I guess i will need to restore it. For now, my iphone is a ios5.0.1 and baseband 4.11.08. So if i put my iphone in DFU mode and click on restore, will my iphone still be in ios5.0.1 and samebaseband or will it update it to ios5.1 and the ios5.1's baseband ?
Because if i restore it with a custom firmware (by clicking on the shift button when i click on restore), i got the error 3194 (i think it's this number, not sure anymore). But it's the error that means that apple can not verify the authenticity of the ispw

Thanks a lot !, I Apriciate it !
