Hey This may be a stupid question but how do I re-jailbreak. I have already Jailbroke (4.0.1) and unlocked using Ultrasn0w. I want to upgrade to 4.1 using GreenPois0n. But how I do properly re - jailbreak. Just hit restore and run the JB? That simple? OR to KEEP your BASEBAND use PwnageTools? Does PwnageTools create my .IPSW customized and then "option+retstore" into iTunes to keep my baseband? BETTER than clicking restore in iTunes and updating that way...right? Please let me know if there is a specific procedure. ANDDDD will I lose my unlock forever? Since obviously the baseband will change (should I use TinyUmbrella, Pwnage to JB?). Can I have until 4.2 and then just unlock to something easier like Ulrasn0w? Thanks!
