The popular iPhone game Angry Birds will not be available on the Windows Phone 7 platform, despite Microsoft announcing that it would be.
Rovio Mobile maintained that it was not developing a version of the game for Microsoft's platform and that the software giant had used the game's icon without its permission.
The appearance of the icon on the list of applications available for Windows Phone 7 was reported by WMPoweruser.
However, the game developer confirmed over Twitter: “We have NOT committed to doing a Windows Phone 7 version. Microsoft put the Angry Birds icon on their site without our permission.”
A Microsoft representative has said that the website was not supposed to go live yet and that the icon was put there by mistake.
Rovio is on the verge of launching the game for Google's Android platform and maintains that, although it has no problems in making the game application available for Microsoft's platform, it is wrong to use another company's IP without permission.
