Back when Sonic CD Achievements was announced last year, it was set to come to XBLA and Windows Phone 7 at the same time, and while the XBLA released as expected last December, the last we saw of the fabled mobile version was last year with the release of a few screenshots. Now, only a mere 11 months after the release of the XBLA version, SEGA have announced that Sonic CD (WP) is set to release on Windows Phone 7 & 8 devices on November 14th. In the meantime, there's always the XBLA version, out now on the marketplace for 400MSP.
