I have an iPhone4 that is jailbroken with redsn0ws 0.9.10b3. My iPhone is currently running iOS 5.0.1. What would I need to do to update to the latest iOS version and keep the jailbreak? Also, if I have to start with a fresh install, how do I recover apps downloaded or purchased through Cydia? These are probably simple questions, but I am new to this. Thank you for your patience.
