I have a 4S running 5.0.1. It's already running a jailbreak and has been for about a month... my apologies for not knowing exactly what I used to jailbreak it. I have Cydia, Winterboard, all that jazz and I just want to clear everything I have installed through the jailbreak and go back to a fresh jailbreak.. if that makes sense. I was just going to Restore through iTunes and rejailbreak but they require that you update to the newest software. Anyone?
