HTC has opened the Mobile World Congress 2009 with two new Windows Mobile touchscreen smartphones they’ve managed to keep mostly under wraps: the Touch Diamond2 and the TouchPro2. 

The TouchPro2 features a larger display than last year’s Touch Pro, a 3.2-inch 800×400 WVGA touchscreen to be exact, which should make mobile web browsing a bit more interesting; it also features a tilted-screen design similar to that of the AT&T Tilt (TyTN II).  Other features include a Qualcomm MSM7200A 528 MHz CPU, 512MB of flash ROM, 256MB of RAM, Windows Mobile 6.1 (with supposed eventual support for Windows Mobile 6.5), a microSDHC card slot, a 3.2MP camera and a 1500mAh Li-Ion battery. 

Expect to see the TouchPro2 in the U.S. sometime this summer.
