Support for Windows Phone 7.8 now runs to October 14th15
After October 14th, those using Windows Phone 7.8 will not receive any updates or new features for their phones. This is nature's way of saying, "Hey buddy, you're due for an upgrade!"
Windows Phone 7.8 was launched in June 2012 and was replaced by Windows Phone 8 in October, 2012. This Summer, Microsoft started pushing out Windows Phone 8.1. You might recall that Windows 7.8 included some features borrowed from Windows Phone 8 such as the small-sized Live Tiles, Bing Lock Screen photo of the day, 20 new themes, Wi-Fi Tethering, and a number of improvements to the camera.
