Let me be a bit more clear about the problem. We are having no trouble with synch. Using all programs and drag and drop transferring music is a snap and goes off without a hitch. The issue is when the phone is rebooted all meta data associated with music loaded from the PC (music pass albums are unaffected, internal memory is unaffected) is erased from the SD card. The songs are there, but they are transferred to a folder marked unknown artist with no album art or name, making it hard to organize to say the least. It's simple enough to resynch, or if using WMP to erase the unknown album folder and reload the music (I put all these albums in a playlist so I don't have to find them again) but loading 15 gigs of music on the phone takes awhile and it's a real pain to have to go through that after every reboot. What's concerning is we have 3 phones now sold thousands of miles apart that are exhibiting the behavior. What's weird is that it doesn't immediately erase the meta data. Coming out of reboot everything looks fine. If you wait about a minute or two you can actually see the albums being erased by the phone. You're looking at the album art and then one by one the albums turn to grey boxes and then disappear. Something else weird. Connected the phone at work and installed the latest build of the Win 7 synch app. Detected the phone, saw the SD was full, but would not detect that any music was present or allow me to pull the songs from the phone. Weird.
