Hi, Let me first of all apologise if these questions have been asked before. I may not of fully understood previous posts. 1. When I restore to factory defaults where does this live? On the ipod? Does it get completely rewritten from itunes? I dont understand! 2. Is it more dangerous to jailbreak from a wireless network? I have seen previous posts saying that people have not been able to recover from a white screen. Is this true? 3. How do I go about updating and managing from version 1.1.2 to the next version? I dont want to loss any data! Thanks for any help on the above.
