Nokia Lumia 900 owners on AT&T have been made to wait an excruciatingly long time for the almost Windows Phone 8 experience in Windows Phone 7.8, but finally the software is rolling out. After months of promises, the 900 is getting a fresh outlook on life with the 7.8 upgrade—new Start Screen with resizable tiles, lock screen enhancements and a smoother overall experience. If the features in the 7.8 update aren’t quite good enough for you, AT&T is currently offering the Lumia 920, which runs Windows Phone 8 out of the box, for free with two-year contract. Basically, if you’re a Lumia fanatic, today is a good day. You can update your device now by following the source link.
