Long Story, not so Short...

I have a 2G iPhone that I stopped getting AT&T service approx 18 mos ago due to not being able to afford it because of personal issues. I was using it frequently as a music device and for other non-related service needs. Recently, things started getting better that I could afford some cell service, but not the near $100/mo for AT&T's minimum call+data package...so I got me a pay as you go SIM and stuck it into an old RAZR.

I recently discovered jailbreaking and unlocking my phone and it works like a charm...I stuck my AT&T pay as you go SIM into the iPhone and I can use my minutes on my iPhone and get wifi internet access...it's wonderful!

However, in my excitement, I believe I may have lost my camera roll forever, with some treasured pictures of my daughter.

I had to restore back from 3.1.2 back to 3.0 and then I used redsn0w. That is obviously when I lost all my personal data and media files on the iPhone. I got all my iTunes music synced back to the phone, however I had assumed that iTunes was saving my camera roll as well...but I can't find the photos, only music.

If I try to restore to a backup point, will that undo all the work I did in jailbreaking and unlocking the phone? I just want to get my old photos and I'm told that iTunes does store them as backups, but I can't find them.

Thanks in advance for any help.
