A classically designed 3G smartphone. It's the lightest and most compact smartphone available, and probably the easiest to use. Equipped with 3.5G for fast web browsing and downloads, this phone is smart enough to do most things you could ask of a phone. Available in black, white or pink.

The 6120 Classic is a classic-looking Nokia finished with attractive chromed highlights (available in black, white and pink). It's a slimline phone with a large screen, and an easy-to-use keypad and 5-way navigation key. Like the very popular 6300, it gives the impression of an old-fashioned Nokia (which is a good thing) as if the company has learned some lessons and is getting back to what it used to do so well - making great phones that do just what you want.

However, looks can be deceiving, because this is no bog-standard Nokia, but a 3G Symbian smartphone. In fact it's the lightest and probably the most compact smartphone available, and the most mainstream one too. The 6120 Classic is a high-spec device, outstripping the Nokia N73 in some respects. The first thing that we note when examining the phone is the display. This is a very high quality display with an amazing 16 million colours and a very high resolution of 240 x 320 pixels. However, this does mean that fonts are small, and anyone whose eyesight isn't as good as it used to be may well struggle with this phone. The camera is rated at 2 megapixels and is nothing special, but the 6120 Classic does also support video calling. The 3G is a fast (so-called 3.5G) HSDPA implementation, enabling download speeds several times faster than normal 3G.

The 6120 Classic is equipped with a music player that can handles all of the common formats - MP3, M4A, eAAC+, and WMA - and there's a built-in FM radio too. Audio quality is good, especially when using the Nokia Stereo Headset HS-47 supplied. With an internal memory of 35 Mbytes, you can store half a dozen songs, but the memory can be expanded to 2 Gbytes with a microSD card, giving the phone the same capacity as an iPod Nano.

One new feature that appears in the 6120 is Text-to-speech. This lets the phone read your text messages and emails out loud. Could be handy if the fonts are too small to read!

As well as being 3G enabled, the 6120 Classic is quadband, so you should be able to use it on any network anywhere in the world. Connectivity is Bluetooth 2.0 and USB, but not infrared. The battery life of the 6120 is below average, and you'll probably need to recharge every couple of days, depending on usage.

The only problems that we can see with the 6120 Classic are the small font size and the below-average battery life. Apart from these two issues, the 6120 Classic is a beautiful smartphone, and a much more satisfying phone to use than most of the Nseries phones. It's neat, it's smart and we like it!

The Samsung X830 (or the Samsung Blush as the pink version has been nicknamed) is a tiny music player phone with a rotating design. There's no doubt that this is a very trendy, cool-looking phone that is packed with features and is a real head turner. Available in black, white, pink and orange, the X830 is one of the smallest and lightest phones ever. When closed, all you can see is the screen and the click wheel used for navigation and controlling the music player. Swivel the phone open, and you can make calls and have access to a full keypad.

Now it has to be said that rotating design phones are not new, and have a sad history. Motorola introduced the V70 and V80 rotating phones a few years back. They were cool-looking phones and seemed good on paper, but were notoriously unreliable and difficult to use. Sony Ericsson's S700i was more successful, with a better design, proving that rotating phones can work if they are designed well. The benefits of the rotating design are that, like a slide phone, you can make a very compact phone with a large screen, and Samsung have really made the most of this with the X830 - it's a tiny phone! The X830 concept does work in fact, thanks to the introduction of the click wheel navigation. This makes it possible to access most of the phone's functions very easily without having to open the phone, and so the device becomes a very small music player/camera/organiser. The problems start when you open the phone to make a call. Because the X830 is so narrow, the keypad is arranged with a strange layout, with keys in unfamiliar places. With a bit of practice you can get used to this, but the other problem is that the phone becomes very long and thin when fully opened and is cumbersome to hold. This is the price you pay for having such a tiny & trendy phone!

• 1.3 megapixel camera with 4x digital zoom
• Video camera (MPEG4 format)
• Display: TFT, 262k colours, 128 x 220 pixels

The Sony Ericsson C702 is a mid-range 3G phone that offers a lot for your money. Its star feature is GPS satellite positioning, combined with Google Maps.

Battery life is excellent too, but the keypad and joystick are slightly fiddly. But this phone is so feature-packed, we're willing to overlook this one flaw. Available in Cool Cyan or Speed Black.

This Walkman phone has everything you need from a music player phone: the latest version of Sony's award-winning Walkman music player, a built-in FM radio, and a 2 megapixel camera. It also has the benefit of 3G video calling and comes in a classic slimline design with an ergonomic keypad and navigation key.

The Sony Ericsson W660i is a nice addition to the Walkman phone range. It's basically a 3G-enhanced version of the fantastic W610i with an improved keypad, although the camera isn't as good.

The W660i is a great looker. It has a classic design, with lovely curves, and is available in two distinctive colour schemes: black or rose red. The phone is slim (but not superslim) and is a good size and weight to hold. The W660i has an easy-to-use navigation key and has nicely-sized tactile keys, which is a relief after so many recent Sony Ericsson phones have suffered from clunky joysticks or small keys - Sony Ericsson haven't put a foot wrong with the W660i in terms of design. The display is a good size and, whilst not as high in resolution as the W880i or K810i, is typical for this price range.

The W660i has a good quality 2 megapixel camera and a video recording option. It can't compete with the camera on the high-end K810i, and is missing autofocus and a camera light. Being 3G, it also supports video calling.

Features of the Sony Ericsson W660i include:

• 3G video calling
• Video clip recording
• 2 megapixel camera with 2.5x digital zoom
• Display: TFT, 262,144 colours, 176 x 220 pixels
• Walkman® player 2.0
• FM radio
• MegaBass™ - enhances bass frequencies
• TrackID™
• Polyphonic ringtones / Music Tones
• Speakerphone
• Sound recorder
• Messaging: SMS, MMS, Push email
• 3D Java games (pre-installed)
• Web browser
• Picture blogging
• RSS feeds
• Animated wallpaper
• Personal organiser functions
• Connectivity: Bluetooth (with support for stereo headset), USB
• Memory: 16 Mbytes plus Memory Stick Micro™ (M2™) support (up to 1 Gbyte)
• Flight mode
• Vibration alert
• Size: 102 x 46 x 14.5 mm
• Weight: 93g
• Triband (GSM 900, 1800, 1900) plus 3G (UMTS 2100)
