When you restore your computer (and put all your stuff back on) and plug in your iPhone again it'll say "this is iphone is synced with another library". You just have to sync up your iPhone again. It will erase what ever you have on the iPhone and put on what ever is on the computer.

You won't lose your jailbreak..
