I am now using 3.1.3 version and want to update to 4.1
I have unlocked my iphone previously by paying o2 15pounds for the unlock. If I update my iphone, Is it going to be locked again?
I have also jailbroken my iphone, if I update it, will I lose my jailbroken apps and what is the best program to jailbreak 4.1?
Thanks!!
