You can now pick up the Nokia Lumia 900 for $49.99 on a two-year contract from AT&T in the US, down from its already-inexpensive $99.99 price tag when the smartphone first debuted in April. If you?re new to the Lumia 900, the phone comes in four colors including pure white, matte black, cyan and the new addition - pink.

The Lumia 900 supports AT&T?s LTE network, has a 4.3-inch ClearBlack AMOLED screen and sports an 8-megapixel camera with a Carl Zeiss lens.

You'll get access to a host of free, Nokia-exclusive experiences such as Nokia Drive (voice-guided, turn-by-turn GPS navigation); ESPN Sports Hub; Nokia Play To (lets you display your photos and videos from your phone onto your TV); The Dark Knight Rises app; and the 100th Day of School.

The phone also runs Windows Phone 7.5, and like all other existing Windows phones, will not be upgradeable to Windows Phone 8 OS this fall.

Nokia is also pushing the upcoming experiences that the Lumia family of phones will still get, including Windows Phone 7.8, with a new start screen, plus Nokia-only features, like DLNA support, new camera effects, and Zynga games like Words with Friends and Draw Something.
