Hey Guys,
iTunes asked me to Download and Update this new thing for my iPod because as you all know Apple can't sit still for more than 3 bloody days without having to send out some pointless update for their stupid stuff.

Anyways,
When I clicked 'Download and Update' it said:

'You have purchased items in your iPod that aren't on your iTunes Library, You should copy these before updating your iPod.'

Now why would it give me that warning unless something horrible was about to happen?

Does this mean if I update my iPod they're going to DELETE all my songs and stuff?
I spent hours the other day pimping this iPod!

What should I do?
I need to update it so I can Jailbreak it, It isn't like most times when I would just ignore iTunes' daily updates.

Have any of you ever gotten that message in bold?
What happened after it?
