Unjailbreaking a phone that can't sync with iTunes
I am a serious amateur here with a very uncommon issue.
I have a Macbook and my software is very old. I have the most recent version of Tiger. I would update to leopard, but my cd slot has been jammed for awhile and won't read anything I put in there. Because of this, my iTunes software is out of date and it won't allow me to sync to my new iPhone 4 which I bought in May.
Anyway, a friend jailbroke my phone for me and I find I don't really end up using it because Cydia is too complicated and confusing for me. Plus, my phone seems more 'buggy' to me since the jailbreak. And today I wanted to start using iBooks but have realized that it won't work on a jailbroken device.
Any ideas on how to unjailbreak my phone without hooking up to iTunes and without losing all my photos/videos, etc??
