The Windows Phone 7 version has still not been released
Microsofts new Photosynth app is indeed a very nice app. It provides a 360 degree panorama by merging shots which have been taken from an Apple i-device. And with the enormous acceptance of the iOS platform, its difficult to understand why Microsoft has chosen to release the new app strictly for the iOS when Windows Phone 7 is having such a hard time competing. No word on when the app will be available on your new WP7 smartphone.
