As usual, CTIA (#CTIAW2012 on Twitter) doesn't start until tomorrow, but the phone announcements are already pouring in.  Aaron gets some hands-on time with the Samsung Focus 2, AT&T's third 4G LTE Windows Phone.  The Focus 2 has a 1.4 GHz single-core Snapdragon CPU, 4-inch Super AMOLED display (480x800 pixels), 5-megapixel camera with 720p HD video recording, a front-facing camera, and Windows Phone 7.5.  Obviously, the specs aren't anything to get too excited about, but the $49.99 price point and LTE connectivity will be great for those looking for a low-cost smartphone.
