The follow-up to the HTC S620 (aka T-Mobile Dash) looks quite similar but it adds 3G HSDPA, a 2 megapixel camera, doubles the clock speed and weighs less. This unlocked GSM Windows Mobile 6 Standard edition smartphone is sold by importers and online retailers rather than US carriers. It's a quad band GSM world phone with triband HSDPA 3G, so it will work anywhere in the world GSM service is available. Like the Dash, it's slim, sexy and sports a QWERTY thumb keyboard. In the US it offers competition for the Samsung BlackJack, various recent BlackBerry models and the Motorola Q9. It has a QVGA display, WiFi, Bluetooth and a 400MHz CPU.
