This unassuming looking handset is, in fact, the smallest and lightest 3G phone that we’ve ever seen. Weighing just 85 grams, the SGH-Z330 comes with a 1.3 megapixel camera, a secondary camera for video calling, 1.9″ 176×220 pixel display, 140Mb of embedded non-expandable memory, Bluetooth, an MP3/multimedia player, email client and web browser. Although some features have been sacrificed to make the SGH-Z330 a lightweight device, it’s still an impressive little handset, with a decent enough camera and plenty of memory to be useful.

The Samsung i320 is a Windows Mobile 5.0 smartphone with a BlackBerry 7100-style keypad, 320×240 pixel display, 1.3 megapixel camera, plus 120Mb internal memory plus microSD expansion and Bluetooth. It comes with all the usual software features you’d expect in a Windows device too.

At 95 grams, this is an impressively lightweight device, and the SGH-i320 measures only 111×59x12mm. It’s a tri-band GSM 900/1800/1900 device with GPRS and EDGE, but there’s no 3G or WiFi support here.

Even though it’s an impressively slim and lightweight device, it’s considerably thicker and heavier than the Samsung X820 which is 6.9 mm thick and weighs 66 grams, but the Toshiba TS608 is more compact than the 85 gram and 12mm thick Motorola SLVR.

One neat feature on the Toshiba TS608 is the top-mounted media controls, something we’ve only seen before on the BenQ-Siemens E61 – this means that you can control the TS608’s multimedia while it’s clipped to a belt.
