I'd expect 3-4 revs before we iron out all the kinks. We haven't done any revs with Nokia yet but we're told it takes 6-8 days. Once our website is up, I think we'll distribute a copy through there to expedite the process. The app currently downloads missing artwork from the internet but try as we may, it will always have some failure rate. We don't have any immediate plans to fix that on the mobile client but we will be shipping a desktop client for mac (available in beta) and windows and linux shortly which will allow you to fix the metadata from there.
