Nokia appears to be making some interesting moves as of late. Following rumors that the company will hazard a foray into the world of digital music sales, the Finnish mobile manufacturer has signed a deal with Microsoft to utilize its PlayReady DRM scheme. The technology, which is file-format-independent, is specifically targeted for use with mobile devices, and is intended to strengthen "security" on a wide variety of content such as music, videos, games, ringtones, and images. The DRM is backwards compatible with the existing Windows Media 10 file management, and will be implemented on upcoming S60 and Series 40 Nokia devices beginning in 2008. It seems at least somewhat possible that this arrangement could be related to the recent whisperings of Nokia's iTunes-esque plans, as DRM has already been hinted at for the supposed forthcoming service. Perhaps on August 29th all will be revealed -- but only Olli-Pekka Kallasvuo knows for sure.
