Music Lost + "Restore from Backup"

Aug 21, 2007

I've read where people have sometimes spontaniously lost music from the iPhone. This happened to me this week. and its not that big of a problem as I have my music on my laptop.

My concern is that, when I connected my iPhone to the laptop it comes up with a screen which is asking me if I want to "restore" from a backup. I am not sure what ramifications this carries with it. So I wanted to see if anyone has done this before, and understand this process before I go ahead and do this.

The reason I worry is that my iPhone is modded with 3rd party apps. I have not cracked it for use with T-mobile or anything like that.

Any insight would be greatly appreciated.

Thank you in advance!
