Motorola announced broad support for Microsoft technology at 3GSM World Congress in Barcelona. Microsoft technologies to be incorporated into future phones include Windows DRM, Windows Media Audio (WMA) file format, Windows Media Audio Professional, and Media Transfer Protocol (MTP). MTP will allow users to synchronize their music libraries between their phones and Windows PCs via USB 2.0.

Once a song is saved by a publisher in secured WMA format, Windows DRM (Digital Rights Management) restricts how and where that file can be played and copied.

Motorola has been using Microsoft technologies on some of its phones in 2005. Microsoft Windows Media-enabled handsets will be available in the second half of 2006.
