Just over four months after the unique device hit Verizon stores, the Sony Ericsson Xperia Play 4G has now made it past AT&T's front door and onto shelves nationwide. The unique factor on this particular version of the "PlayStation Phone" is the inclusion of 14.4Mbps HSPA+ -- with enhanced backhaul, naturally -- and will be the first PlayStation-Certified smartphone on AT&T's network. At $50, the pricing is certainly competitive since it ships with Android 2.3.3, a 1GHz single-core CPU, Adreno 205 GPU, 4-inch 854 x 480 display, and seven pre-loaded games. At a full $150 less than Big Red's launch price, the carrier may move a few units. If you're one of those that could be persuaded, head to the source link and get your shopping on.
