My iPhone 4S is currently happily running iOS 5.0.1 and jailbroken. It has a lot of music, Apps, cydia tweaks etc. so I am reluctant to restore to a fresh iOS 5.1.1 and rejailbreak and then add everything back. Can I just update (not restore) to 5.1.1 using itunes and then update cydia for 5.1.1 with Rocky Racoon or will it error out because of the jailbreak?? On a related note, is there any real need to update to 5.1.1 if iOS 5.0.1 seems fine? What are the chances of Apps needing 5.1.1 as opposed to 5.0.1? I do have 5.1.1 blobs saved for the 4S- with the 4S, will that work for allowing an update to 5.1.1 after Apple stops signing it? I know it works for older models not sure with the 4S... Thanks!
