| | Can I upgrade to version 1.1.1--please read and HELP! :-)
I have a legit iPhone activated through AT&T
However, I had it unlocked to accept my Rogers SIM card. Turns out...Rogers SUCKS and I don't have access to much of anything other than the phone.
Long story short, I am using it as an AT&T phone exclusively now, but I want to update my version to 1.1.1
(I like to keep software current to take advantage of any fixes)
I don't care if it disables the unlock...I won't be using it any more anyway...but will it mess up my legitimate subscription to and give me a brick?
Any advice is appreciated....
