Is there any possible chance that copying an entire iPhones file system into a .ZIP file and then turning that into an .ipsw would actually work? I would really like to be able to try something new with my jailbroken iPhone but would regret losing all the hard work I've put into theming it. I was wondering if it was possible to do this? and even more could you restore from it and the device would still be jailbroken with all the tweaks, themes and so on still on it.
