I have an I Phone 3 GS with 4.3.1 version. It was locked by AT&T when I bought it then the seller jailbroke it.
Now I want to upgrade it but I don't want AT&T to catch me. Can someone help me first how to back up my device (I have Cydia too) then upgrade and lasty, jailbreak again? Also which version can I upgrade?
Thanks for your help!!
Connect to latest iTunes and click restore. It will restore to 6.0.1. To jailbreak, use redsn0w 9.15b3/extras/select ipsw/browse for predownloaded 6.0 ipsw then redsn0w/jailbreak/install cydia.
