While you're out buying goods for your Memorial Day barbecue, why not swing by Best Buy and pick up a HTC Touch Dual? Yes, the Touch Dual will be available in stores and online starting this weekend for a nice chunk of change--$549 to be exact. First announced at CTIA 2008, the Touch Dual alleviates some of the text entry pains of the original HTC Touch by providing a slide-out SureType-like keypad. It will also be the first Windows Mobile 6.1 device available in the United States, and also features support for U.S. 3G bands (HSDPA 850/1900), Bluetooth, and a 2-megapixel camera. The HTC Touch Dual will be sold as an unlocked phone, so you can use with an AT&T and T-Mobile SIM cards.
