Hey guys I'm new here and I need some help. I have an iPhone 4 on Verizon's network. I have it jailbroken on 4.2.6 with Greenposi0n. I'm getting tired to the jailbreak and I want to get rid of it. Only reason that I have the jailbreak in the first place is to have infinifolders. I want to upgrade to iOS 5 and I need to know how to do so. I do not want to lose anything that I have to my phone. I have over 1,500 photos and quite a few contacts that I need badly. Would I just need to upgrade the firmware or would I have to do a full restore? How would I be sure not to lose my photo's, contacts ect? Thanks for the help.
