Updating to 2.0 Firmware from another computer?

[iPhonedHome]

I'm out of town and want to get the 2.0 firmware as soon as it is up on iTunes. Problem is i'm on another PC. Would I be able to update without syncing?

Also does anybody know if it erases everything when you update the firmware. If so I guess I'll have to wait until I get back to Dallas.

yes it erases everything. do not try and update. wait till you get home

I have a similar situation and I dont really care about my media being deleted. I am worried about what effect buying apps with my temporary account will do. Will I be able to transfer them to my primary account or will I have to buy them again?
