Hi I want advice on upgrading to 2.0

There are several apps in the app store that I want and thats my main reasn for wanting to upgrade.

(I gather from some of these threads that people dontlike 2.0 though)

However I am on a road trip right now and dont have my computer with me. I dont want to lose my music in the upgrade as I wont be able to upload it again for weeks.

Is there a way I can synch to another computer and upgrade without losing my music?
