April 8 is shaping up to be a big day for AT&T and Windows Phone fans. Joining the already announced Nokia Lumia 900 on that date is the HTC Titan II, which will retail for $199.99 with a new two-year contract. The Titan II is an evolution of the Titan smartphone that was released last year, and it features a 4.7-inch WVGA display and all-new 16 megapixel camera – the highest resolution camera in any smartphone available in the U.S. The Titan II runs Windows Phone 7.5 and supports AT&T’s 4G LTE network.
