  • Is it possible to safely and easily unlock an iphone 4s by yourself? I'm looking for a 4s but I realize that the unlocked ones go for more so I wanted to know if I could factory unlock one by myself without having to pay… Or is there a place where it is safe and cheap to get it unlocked? I just don't want to mess up my new phone. Also can you jailbreak it yourself but also be able to update the phone's firmware while it is jailbroken? (That means without having to reset it every time a new version after ios 6.1.13 comes out).
