iPod touch backup 1st gen 16gb without using Itunes

[Importroller]

I want to upgrade my ITouch but I don't want to redo all my folders for music. I tried to backup using itunes but it keeps saying the ipod is disconnected so it wont back up. Its jailbroken currently, so i dont know if that is why. can anyone tell me if there is another way to back it up

i think theres jailbroken apps that lets you backup your stuff.

The problem is once I update it to the 3.? it won't be jailbroken anymore, so the backup will be gone. I need to know how to back this up to my PC and then put it back on the IPOD once its done.
