It's been out on Verizon for some time now, but the addition of 4G (HSPA+) and a $150 price drop can't hurt, right?  Shown off earlier in the summer, AT&T is rocking the Sony Ericsson Xperia Play 4G, an Android device with a 1 GHz processor, 4-inch display, 5-megapixel camera, a front-facing shooter for video calls, a built-in Playstation controller, Android 2.3 with Sony Ericsson's Timescape UI, and seven games.  It ships with a multimedia dock and a bunch of other goodies, making it a very attractive handset with a sub-$50 price tag.
