Among the various problems users have encountered with the new iTunes 7 software, one of the worst has to be the fact that the iTunes Music Store purchases aren’t working in Motorola ROKR and SLVR phones. The songs that have been ripped from CDs or downloaded as MP3s from elsewhere on the web work fine, it’s just the DRM tracks from iTMS that don’t work.

No fix has been found yet, but Apple’s working on an updated iTunes 7 that should be released soon. In the meantime, if you haven’t upgraded, we suggest that you wait.
