When the iPAd downgrade was released i down grounded. So now i can update threw itunes, which is awesome. The thing is i'm on straight talk and still unlocked with no JB. Don't know how this happen but im loving it. I never used a unlocking service. I have had this 3gs since 4.1. Anyone have any idea how this happen. Trust me i am not complaining. Just a lil puzzled.
