AT&T is running a very co-op friendly deal on their Windows Phone 7 devices, something we looked at briefly when it was announced thanks to its Xbox Live integration. We've been hearing good things about its marketplace, with an ever growing catelog of games, it won't be long now till we start seeing some cooperative titles to play.
Right now you can snag yourself any Windows Phone 7 device AT&T offers and get another one free, a perfect New Years gift for your co-op partner. They've thrown in a free Xbox 360 game of choice to sweeten the pot, both great co-op titles in Halo Reach or Fable 3.
With two phones in hand you'll be ready once the co-op games begin to roll out on the platform! For more info check out the official website.
