The c6620 is one of the new phones that Samsung showed off last month at Mobile World Congress. That didn’t take very long at all. This new model resembles the ever-popular BlackJack line of smartphones running Windows Mobile Standard 6.1. The keyboard has a slightly different design and the keys look to be a little shorter in height. The screen is larger at 2.6” compared to that of the BlackJack II with 2.4”. The biggest difference is in the radio. The c6620 only sports a Tri-Band GSM (900, 1800, 1900) and a single band 3G / UMTS (2100), making this device all but useless here in North America. I hope Samsung has more up it’s sleeve, because this seems to fall short.
