I hope you get some good feed back. I recently added a 1G microSD to my Pearl and thought I could sync it as a device using Media Player. Media Player saw it and dump a bunch of MP3 files on to the BB, but the BB did not see them.
I thought it was a “wrong directory” problem so I tried using the BB Desk Top Manager which would not recognize the media card while I was connected. I then used Window’s Explorer and found the device with 4 directories and selected audio and drug and dropped about 50 files, which would have overfilled the device memory. To my surprise they all copied. When I disconnected the BB and selected media, audio, media card, they were all there!!!!
I was worried about how to set the proper directories and BB just automatically did it. Now I have the songs but it would be nice to have a media player to manage them.
