I am waiting for an updated iOS 4.1 jailbreak so I can update to it. When I did the last update I wiped out my jailbreak. Had to downgrade and go throught the enitre jailbreak process from scratch. I was pissed as it took a long time to get phone back to the way I had customized it. How do i avoid this from happening when the new jailbreak comes and I update my OS? Thanks!
