    It's a bit of a long story, but here goes:

    I have an iPhone 3GS that was unlocked (jailbroken). I updated to OS5 without realizing that my phone would no longer work. Before I had updated, it had asked if I wanted to backup my phone - which it did in the following directory: name/Library/iTunes/Mobile Backups/<serial number>/Structured

    I was not able downgrade the OS (I kept trying to downgrade to 4.3.5). Anyway, I took it to someone paid $20 and had him put iOS 4.1 on it. I have a firmware of 6.15.00.

    Now, I have the phone unlocked again on iOS 4.1 and I need to restore my information. I copied the contents from the above directory into a previous restore under /Library/Application Support/Mobile Sync/Backup/<random directory> - so it shows up in the restore list in iTunes.

    The problem is if I restore the backup it will update to iOS5, correct? How do I get my contacts / pics / calendar, etc back on my phone without updating to iOS5 and screwing this all up again? I can't keep paying someone $20 to unlock my phone everytime I mess up.

    I also downloaded the iOS 4.1 file now in case I need it. And I restored my stuff on a friends phone who has iPhone 4 with OS5 - so I know all my information is there.

    Can someone please help?

    It looks like if you just restore to a backup it doesnt update the OS. I took a chance and it worked. phew.
