When Microsoft said that it would release its Remote Desktop app for Android and iOS, it left many scratching their heads -- what, no Windows Phone version? There's no need to worry, though, as the company has just promised The Next Web that it's writing a client for its own mobile platform. Redmond can't yet say when it'll release the app, although we wouldn't expect a launch in the near future. Microsoft got a head start on developing for Android and iOS by acquiring technology from HLW Software, which produced Remote Desktop equivalents until this month; there's no such luxury for Windows Phone.
