I had to jb my iphone 4 for the second time. I'm using the 4.0.1 firmware. I'm confused about the whole itunes after jailbreak relationship. I already know NOT to hit update on itunes. However I don't know any of the other rules. When I hooked up the phone to itunes after jb it says "an iphone has previously synced with this computer" I can either set up as a new phone or restore from a back-up. QUESTIONS: 1. Can I upload my contacts, photos, music, and apps with itunes after my JB? 2. If so, which option do I chose, Set up as new phone or Restore from a Back-up? 3. If the answer is restore from a back-up, then what time period do I need? Time period before any of my jailbreaks? or time period of when I had my 1st jailbreak? 4. For the future is it ok to back and sync my Jailbroken phone with itunes or will either of those lose my jail break? 5. Lastly, is there anything else that I haven't mentioned that can ruin my jailbreak with itunes besides updating the newest firmware? THANKS IN ADVANCE!!!! Sorry I'm a bit paranoid of losing my jail break again!!!!
