The HTC Touch Dual will soon arrive at Best Buy now that FCC gave it a thumbs up. It will be sold exclusively through Best Buy as an unlocked GSM phone with support for 3G support

The HTC Touch Dual is the upgraded version of the highly popular HTC Touch. The Touch Dual adds a slide out 20 key keyboard, and of course, 3G in that sweet HSDPA flavor. This version lacks international 3G bands, and it is possible it is only for sale in North America.

The reason for this could be so that a clear differentiation between the European model and this can be made. It could also help cut costs, as this is no budget phone. It will have all the features we know and love on the previous Touch, such as TouchFLO, but adds that keyboard, and will ship with Windows Mobile 6.1.
