I was seriously considering ditching my Blackberry for this phone until I read that you cannot play music on it. There is no music player and no file management feature to find/use .mp3(or the like).... With that massive external speaker setup that should have been a priority element.
To bad I didn't see this message a while ago because you can use DuraXT with a microSD card and transfer non protected songs from your computer to the device or via Bluetooth. The phone has a feature called memory storage, and within that area is how you can play music. You can download the full user guide at http://www.duraseries.com/downloads.html
