T-Mobile USA has tweeted today that the Samsung Galaxy S III is their best selling device of all time. This is no surprise considering the popularity of Samsung's Galaxy series of smartphones and is very promising for Android. The device is likely to be Samsung's flagship for at least another 6 months, so T-Mobile USA is likely to expect many more orders. Did you know the Samsung Galaxy S III is @TMobile's all-time best-selling device? RT if you love your device! Microsoft is likely hoping that Samsung can match the success with it's upcoming Windows Phone handset, the ATIV S. The device looks almost identical to the S3 but will run Windows Phone 8 instead of Android. The smartphone was the first device to be announced that will run Microsoft's latest mobile OS and packs a 4.8-inch HD Super AMOLED display, a 1.5GHz processor, 1GB of RAM, an 8 megapixel rear camera, and a 1.9 megapixel camera on the front.
