There seems to be a common theme today of Windows Phone 7 apps that are clones of popular apps found on other platforms. First we gave you the Angry Birds clone and now comes word that Bubblegum will bring Instagram-like photo sharing to Windows Phone 7. The app was developed by two Microsoft employees in their free time.
The service was scheduled to go online tonight. Let us know in the comments or our Windows Phone forums if you check it out.
