The HP iPAQ 914c (£369 inc. VAT) is part of the company’s Business Messenger range, and is similar in style to the original RIM BlackBerry.

At one time, HTC made handsets for other companies, but it is increasingly making a name for itself in the Windows Mobile space. The Touch Diamond (£450 inc. VAT) has a high-gloss finish and the faceted design on the back helps give it its name. The quality of the plastic used is variable, as the back of the device is solid but we found the front a little less robust. The glossy finish also means you’ll be constantly polishing the 2.8-inch screen.

Nokia has released two very similar Symbian business-oriented smartphones recently, the QWERTY keyboard-packing E71 and this slim slider. The phones have very similar specs – they both run on Symbian 9.2 OS, both have the same 3.2 megapixel camera, Wi-Fi and A-GPS, virtually the same on-screen display and a host of identical apps. The only real difference in fact appears to be size (the E66 is less wide, but the E71 is slimmer) and the E71's QWERTY keyboard. They're even available for roughly the same price.

Motorola's music phones have never really been the last word, but there has been an evolutionary arc of sorts, with a pretty consistent range of improvements from the E1 to the latest E8. But as is often the case, with one hand Motorola giveth, and with the other they taketh away

Sony Ericsson has proved itself to be no slouch when it comes to developing innovative handsets in the past. But a quick look at the C902 gives the impression that it's gone back to basics with a straight-ahead candy bar style handset.

This is a 14K gold-plated bezel for an iPod touch that has a continuous row of Swarovski crystals encrusted into the upper edges to create a diamond effect.

When the original iPhone launched, the tendency was to forget about its faults. So can the new Apple iPhone 3G overcome them and soar to hitherto unforeseen heights?

When it comes to beautifully designed, do-everything touchscreen smartphones, the iPhone understandably takes the lion's share of the attention. But while other devices have exceeded the iPhone's spec, few have come close to its styling or usability until the HTC Touch Diamond.

Updated BenQ isn't a power player in the European mobile phone market and its new E72 handset (announced at Computex) isn't a mass market smartphone.

Updated Not the first choice for camera or music player, but as a do-everything smartphone with sat-nav, it takes some beating

The N78 may not be the priciest example in Nokia's N-series of 'multimedia computers', but this Symbian S60-powered smartphone manages to cram in a serious amount of functionality, including a 3.2 megapixel camera, quality music player and GPS sat-nav technology, all in a compact case that is a serious looker

LG has made good capital out of its Chocolate series with its hidden buttons and it could be said that most of their handsets since have been a variation on that theme. But if it ain’t broke, why fix it, and while the prosaically named KF510 dispenses with the Chocolate moniker, but it’s certainly taken on some of the Chocolate style.

Sure, the iPhone's great, but there's a lot it can't do. And despite the clever use of cellphone mast and WiFi triangulation, one of the most important iPhone omissions is proper GPS.

Samsung’s latest top handset, the Soul SGH U900, follows on from its ‘Ultra’ series of ‘thin-as-they-can-make-’em’ handsets, is a slick slider in a metallic case that just screams classy cool. Or at least conveys its message in moderated yet forceful tones in keeping with its smart but casual designer suit. This is a stylish handset that will grab the attention of the connoisseur, without troubling the flash man-boys of the wannabe brigade.

If you think you need some extra motivation to get fit, Samsung and Adidas think they have the answer – a mobile phone with a personal trainer built in. The Samsung F110 miCoach, a sliderphone developed with Adidas, is designed with personal coaching right at the heart of the phone’s functionality.

The LG KF700 looks like a familiar touchscreen phone – the front dominated by a large 3-inch screen with no buttons to be seen. But LG has equipped it with a slide out numberpad at the bottom for more conventional number dialling and text tapping. In addition, this triple-action phone has a novel Shortcut Dial on the side for quick access to a bunch of functions and applications, and for menu scrolling and other operational duties

We’ve been waiting for a bit of slimline 3G flip-phone action from Sony Ericsson, and with the classy-looking Z770i, it has delivered a very pocketable device with plenty to get your desire buds going. The Z770i arrives as one of Sony Ericsson’s few real clamshell eye-catchers. It has high-speed HSDPA 3G connectivity inside, boosting download times and browsing slickness on its full web browser.

Palm’s latest in its long line of smart phones is also its smallest, and probably its best looking. It’s also returned to the Palm operating system that the company seemed to temporarily abandon with its recent run of Windows-based handsets (that would be the Treo 750v and 500v, in case you’re wondering).

The latest in Sony Ericsson’s K-series, the K660i, certainly won’t qualify as the company’s most advanced to date, with no Cyber-shot camera or Walkman music player. It does however have HSDPA-enabled 3G capability, pretty much the fastest mobile internet access you can get at present, which comes in very handy for showing off its internet browser innovations

If you’re looking for a new mobile that’s environmentally sound then Nokia is hoping the 3110 Evolve will be up your street. The Nokia 3110 Evolve is essentially last year’s 3110 Classic with an eco-friendly makeover that includes covers made partially from renewable materials, an energy-efficient charger and greener packaging

Sony Ericsson seems determined to cover all bases with its Walkman phone range, with the budget Sony Ericsson W380i its latest attempt to corner the low-cost music mobile market. Hot on the heels of the up-market ultra-slim W890i and multi-gigabyte packing W960i, the clamshell W380i delivers a more modest line-up of features at a considerably more wallet-friendly price – initially around £80 on pre-pay or free on contracts.

Nokia has never shied away from cramming in stacks of features and cutting edge functionality into its high-end mobiles, as its N95 8GB and forthcoming N96 testify. With its luxury line of handsets though, such the 8800 Arte, it takes a more refined approach. The emphasis here is not primarily on feature count, but on build quality, design – and, of course, desirability.

Every major mobile phone maker may be trying their hand at touchscreens in the wake of the iPhone, but with the KF600 LG has managed to come up with a touch-controlled phone offering something distinctly different. To start with, LG hasn't opted for full, large screen touch operation, like Apple's iconic handset, and LG's own successful Viewty. Instead, it has introduced a novel twin screen hybrid arrangement on a sliderphone chassis.

Slipping the stylishly slim W890i music mobile into its Walkman phone line-up, Sony Ericsson is aiming to repeat the W880i’s feat of combining classy minimalist design with crowd-pleasing functionality.
