Is there a way to do a fresh jailbreak without going through the restore process? My phone has had several issues, some that seem to disappear then reappear without reason (nothing installed, no resprings, no theming, just there then gone again), and considered restoring with 5.1 but want to give a jailbreak a third chance. However, I don't want to take the hour or so it takes to restore and rejailbreak as I'd like to get this done before work later today. Any suggestions? I have an iPhone 4, currently on 5.0.1. Mac.
