You will lose your jailbreak if you upgrade as an iOS 7 jailbreak has not yet been released. If maintaining your jailbreak is important to you, you should stay where you are until the new jailbreak is released."iOS 7.0-7.0.4 is safe to upgrade to if you're looking to jailbreak." what does that mean? does it mean I can upgrade and I wont lose jailbreak? I'm on 4S with 6.1 Thanks in advance![]()
