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.

The SGH-P900 (pictured) is an unusual looking phone that is slightly reminiscent of the Samsung Z130, with an unusual rotating display. However, the display on the SGH-P900 is designed for digital TV rather than video calling.

The Samsung SGH-P900 is a tri-band GSM device with GPRS and EDGE, a 2 megapixel digital camera, T-DMB receiver, 240×320 pixel display in 262,000 colours, 128Mb of internal memory plus microSD expansion, an MP3/AAC player, dual speakers and Bluetooth. It’s a large device for a GSM phone, at 95×48x27mm and 124 grams, but substantially lighter than the Nokia N92.

Positioned one notch above the lightweight Z500 3G phone in Samsung’s range, the SGH-Z520 has a 240×320 pixel display main, 2 megapixel primary camera, 40Mb of internal memory with microSD expansion, and MP3/multimedia player, inbuilt “digital power amp” and Bluetooth. There are external media controls too, so the Z520 can be used as an MP3 player when closed.

This swivelling clamshell comes with a 3.2 megapixel camera, a 2.2″ 240×320 pixel display, Bluetooth, 128Mb of internal memory with microSD expansion, an MP3/multimedia player, FM radio and TV output. Being a “Z series” handset, this is also a 3G phone.

There are a few camera phones around like this – designed to look as much like a dedicated camera as well as a phone, and the Z710 certainly looks the part, although there’s no optical zoom on this device. Physically, the SGH-Z710 measures 96×48x20mm and weighs 107 grams.

The Samsung E420 is a low cost member of Samsung’s “La Fleur” series of fashion phones with a 128×160 pixel OLED display in 65,000 colours, a VGA resolution (0.3. megapixel) camera and that’s really about it, apart from the E420’s attractive looks.

In fact, it’s the SGH-E420’s looks that give the game away – the interior and basic specifications mark it out as an upgrade to the Samsung X400 (see below) from 2003. Yup, this is essentially a three-year-old phone with a bit of a facelift and a few new features.

The SPH-P9000 is an EV-DO (3G CDMA) device with WiMAX (802.16) support, which means that the SPH-P9000 had high-speed data access wherever it can get a WiMAX or EV-DO signal.

It’s a hefty beast, weighing 560 grams (1lb 2oz in old money), and it measures 143×92x30mm (5.6 x 3.5 x 1.2 inches). There’s a novel folding keyboard, and the main display is a 5″ 800×480 pixel unit, and there’s a 1.3 megapixel camera facing the user. Internal storage consists of a 30Gb hard disk and the SGH-P9000 has Bluetooth too.
