Motorola V710

I recieved my usb data cable in today so I flashed my phone with the new SD firmware. Everything went great and worked well with MPT but it took me 10 minutes to transfer a standard MP3 file to my phone. My younger brother and sister got v551 for christmas from cingular and they can transfer files via MPT bluetooth almost 10 times faster. Now I realize that the v551 has the OBEX profile and the v710 does not, but my question is has anyone esle experienced this slow transfer rate, and is there away to improve it? It's almost not worth using bluetooth via MPT to put mp3s on your phone because it's transfer rate is to slow.

thanks,
