    Hey guys. I needed some help unjailbreaking my iphone 3gs with version 3.1.3 software. I've been looking all over the place to find a thread that suits my problem, but none have really shot out in my eyes. If anyone could please take me through a step by step procedure on how to unjailbreak my iPhone that would be awsome. Also, do I lose all my data? Such as contacts, songs, pictures, notes, etc? If someone could explain in extreme detail that would be great. Thanks!

    DFU mode restore it. Contacts, songs, pictures, etc. should be backed up when you sync your device with iTunes.
