I apologize in advance if this was already discussed, it's a lot of information to go through. I recently upgraded from a touch (jailbroken with screensaver hack) to a pw4. Unfortunately it got upgraded to fw 5.12.1. I would really like to do the screensaver hack again, do I have to jailbreak first? And is it even possible with fw 5.12.1? I'm guessing there's no way to downgrade fw?
Thanks!
