Microsoft to buy mobile music company Musiwave.

"Musiwave allows mobile operators to offer self-branded music applications, including full song-over-the-air downloads, ringtones, and ring-back tones. Operators including O2, Vodafone, T-Mobile, Orange, Telus, Telefonica, and Virgin Mobile are among Musiwave's customers... Microsoft would acquire Musiwave from Openwave, which bought the company in 2005 for more than $121 million."
