Samsung is taking on Motorola as it expanded its Ultra line of slim phones at the Hong Kong’s ITU Telecom World 2006. As a starter, it came up with the Samsung Ultra Messaging i600 as pretty much a direct competitor of the Motorola Q product link.

One of the i600 main features is it runs on Windows Mobile 5.0 with Windows Media Player 10 and is the first 3G smartphone with GSM/EDGE, HSDPA (High Speed Downlink Packet Access), MS Push email, PDF viewer, RSS reader, speakerphone, Bluetooth 2.0 with EDR and A2DP stereo audio support support.It measures 11.8mm thick which might be the slimmest 3G smartphone with a QWERTY keyboard available around. The i600 has a 1.3 Megapixel at the back and a VGA in the front for video conferencing.

The i600 is comfortable to hold and has a soft finishing which makes it easy to hold and best of all it weights only 99-grams (3.5-ounces).
