Sony is to bring 3D to the PlayStation 3 this summer, according to John Koller, Director of Hardware Marketing for Sony. In an interview Koller revealed that the console's 3D plans were on track for a summer release, in time for the company's 3D TV range to hit shops.

The HTC Legend is in second place, costing £399.99, followed closely by the HTC HD Mini at £349.99. All HTC handsets have a 12 April UK release date.

Now 3 announces HTC Desire for UK

3 has decided that it will also be releasing the HTC Desire for the UK - long after it rivals did the same thing. The HTC Desire was unveiled to the world by the Taiwanese manufacturer on Tuesday, and T-Mobile, Orange and Vodafone instantly announced they would be stocking it in the UK. O2 exclusively revealed to TechRadar it would be doing the same thing the next day, but now 3 has decided to join the party as well.

Uncharted 2 sells as many copies as PlayStations in the UK

Bada-based Samsung Wave breaks out

Samsung has announced the Wave, it's first handset based on the opinion-dividing Bada platform. Platform aside, the handset features the latest-gen TouchWiz 3.0 interface (looking more like the iPhone than ever) and a full 3.3-inch AMOLED touchscreen that Samsung claims gives "the best ever viewing quality on a mobile."

35 cool and fun things to try with your PC

Spreadsheets, word processing and databases. Limiting a modern PC to running these bread and butter tasks is like buying a Ferrari and driving it to the corner shop. The question is, with a fast processor, a quick internet connection and a little imagination, what can a PC really do?

10 best free iPhone games on the planet

Although great games are the driving force behind the success of Apple gaming, low prices have also helped. Most 'premium' titles cost six quid or less, and many developers end up in a race to 59p, thereby providing games that'd cost 20 quid on a rival platform for the price of a Kit-Kat. But what if you've spent your last penny on your shiny Apple object of desire? Can you get great games for nothing at all, or is the 'free' section of the App Store full of the kind of games that would make a ZX81 blush?

HTC Legend vs HTC Desire vs Google Nexus One

The days when the T-Mobile G1 was the big cheese in the Android world are happily gone. Now, the Android OS is being used to create some truly industry leading handsets and HTC is behind some of the best. But which is the one for you to spend your hard-earned on? The Hero-a-like Legend? The insanely powerful but stupidly monikered Desire? Or do you trust your mobile dollar in Google with the Nexus One?

The truth about the 50p per month broadband tax

Introduced in the Pre-Budget Report in November, this "Landline Duty" will be enforced from 1 October 2010. A second consultation, drawn up by the Department for Business, Innovation and Skills (BIS), closes on 1 April and will decide how it's spent. It's a good time, then, for TechRadar to look into exactly what this new charge is designed to achieve in terms of improving access to the broadband network, and who gets what kind of service now.

10 things Google should change for Nexus 2

In the wake of our recent Nexus One review, it became obvious that comparisons to other models, including one unmentionable godphone, are raising some ire. The common view: review the phone for its actual features, not what it lacks! And yet, using the Nexus One does inspire these comparisons – like driving an automobile that is almost astounding and therefore reminds you of what the vehicle lacks. Could Google somehow create a better phone in the Nexus 2? Yes, and here's how.

Samsung R720

Samsung was the first manufacturer to release a truly affordable Blu-ray laptop and has continued this trend with such machines as the R720. Combining power and usability, this excellent laptop is a great choice for people looking for a laptop with the latest tech but want to save a few quid.

Philips 46PFL9704H

Using LED backlighting in LCD TVs is no longer news. Over the last few months we've seen a flurry of new TVs from a growing number of brands all exploiting the technology. Yet the Philips 46PFL9704H makes LED feel all shiny and futuristic again, simply by virtue of how damn good it is.

Panasonic Viera TX-P50VT20

The Panasonic Viera TX-P50VT20 will be the very first 3D TV to hit UK shores and it's a masterpiece. We got our first look at the £2,000 3D TV at Panasonic's annual launch event in Munich this week - it's certainly a great-looking set, and well-specified too.

HTC Legend

The HTC Hero has been around for a while, and we're waiting for an upgrade. Well, here it is - the HTC Legend, squarely picking up where the Hero left off. HTC is trying to make out to us that the Legend is not the direct sequel to the Hero, but rather a continuation of the 'baseline' set by that successful handset.

HTC Desire

The new HTC Desire is the phone that's got many an Android fan hot under the collar - packing top end hardware into a thin chassis. Those that watched the Nexus One announcement unfold but wished that HTC had plugged its cool Sense overlay onto the phone will be pleased, as this is what the Desire is all about.
