Okay, sorry if this is a dumb thread, but I just want to play it safe: I am on 5.1 tethered jb on ip4. If I want to upgrade to stock 5.1.1, can I just do a normal iOS upgrade through iTunes if I don't care about keeping the jb? What about my texts, contacts, photos, etc? Will they still be there if I just do a straight upgrade through iTunes to 5.1.1? Again sorry of this is a dumb question, but it's my first iPhone and first time updating iOS version on a jb iPhone.
