Thanks to WP Central, we have learned that developer, Bil Simser has been working on an Instagram program for the Windows Phone, titled Metrogram. If you do not know, Instagram is a popular photo app exclusively for the iOS(iphone, iPod, iPad, etc) that allows you to take pictures and add filters to them. You can then share them with your Instagram followers as well as upload them to Twitter or Facebook. It is unknown if Instagram will accept the development of a Windows Phone app as Bil Simser’s Metrogram program is an unofficial development of the original Instagram. Let us know what you think in the comments below, we are certainly crossing our fingers on this one.
