Microsoft isn’t making a music-focused ZunePhone. Really. At least, that’s what the company has reiterated, following online speculation. “Microsoft is not going into the phone hardware business. Microsoft is not building a Zune-specific phone.” is the quote from a spokesperson. However, as Engadget points out, this doesn’t rule out Zune being integrated into Microsoft’s Windows Mobile smartphone platform, allowing it to be offered across handsets from a range of manufacturers.
