In the processing of jailbreaking an iPhone 4, methods would call for restoring iOS 4.2.1 on the iPhone. For example: http://www.iphoneheat.com/2010/12/u...ne-4-ipad-ipod-touch-4g-with-redsn0w-0-9-7b1/ One headache I always have is that restoring wipes out all apps that I have installed and organized in folders to my liking. Sure, I can reload these apps onto my iPhone. But, I then have to re-organize them. I guess there is no way around it.
