so my 2 year contract is up on my iphone 4, and i received the official unlock from ATT. i have to restore it on itunes to get the official unlock. but i want to stay at 5.1.1. i have the shsh blob saved so i know i can get it signed on the saurik's server, but will it unlock the phone? do i *need* to get it signed by the apple server in order to get the unlock? i'm not sure how this unlock thing actually works... or do i have to go to ios6, get it signed by apple, then downgrade to ios 5.1.1? this sounds like a nightmare to me... any thoughts/comments are appreciated.
