Upgrade to 2.0 loses phone-purchased music?

[randyhudson]

I just upgraded to the 2.0 software after returning from vacation. An Album I purchased on vacation was lost during the backup/restore procedure. Is this normal behavior!?

During the upgrade, my wife logged in to use Skype, and at some point iTunes opened automatically, I think at the point where the phone boots up with the new firmware and tries to connect to iTunes to restore itself. This may have contributed to what appears to have been a botched restore.

Upgrading the firmware erases everything on the phone. If you didn't do a phone backup & restore, or you didn't sync the purchased music before you did the firmware upgrade, then you'll have lost the music (and any notes, contacts, pictures, etc., that you created before your last full sync).

The iTMS help people may authorize you to re-download if you call them.

I'm pretty sure backup is done as part of the update, but the "backup" maybe is only your application data, and not your music. It seems trivial for iTunes to check for music which is on the phone that has not been transferred over to your iTunes library, especially since you can only sync with a single itunes+user instance.

Are you sure the upgrade erases everything? I thought the music was on a separate partition from the OS.
