I figured if I updated my iTouch to this new update it wouldn't harm my jailbreak because it was so little. I thought only firmware updates restore your iTouch, but I was wrong and now I'm un-jailbroken again............. I did back-up with AptBackup, but how can I use that to get all my stuff back if AptBackup is gone, too? Ugh I'm so annoyed right now. Little help for an iTouch newb?
