Tesco: Android has overtaken iPhone
Tesco has revealed that the sale of Android phones on its network have surpassed Apple's iPhone for the first time.
Tesco, a virtual mobile operator running on O2's network, says its customers indicate that Google's operating system is poised to grow even larger in 2011.
In the pre-Christmas period the iPhone was outselling Android smartphones by a factor of two to one, but January saw what Tesco is describing as a 'rapid increase' in Android sales to gain parity.
And February has seen Android overtake iPhone sales, although it should be pointed out that the new iPhone 5 UK release date is likely to be in July, and could shake things up once more.
Leaked images of iPhone 5 cases surface
Mock-ups of a case said to be made for the iPhone 5 have hit the internet.
If these are indeed cases made for the new Apple handset, the iPhone 5's design seems to vary very little from that of the iPhone 4.
Tesco Mobile blocking iPhone Wi-Fi hotspots
Tesco Mobile is currently blocking the portable hotspot feature in the new iOS 4.3 for the iPhone 4.
The update, which was revealed at the same time as the iPad 2, lets users send their data allowance from their phone via Wi-Fi signal.
However, some TechRadar readers complained the portable hotspot feature wasn't there on their Tesco Mobile-powered iPhone 4, despite updating to the new iOS.
Sky launches affordable HD multiroom box
Sky has launched what it is calling an 'affordable' HD box for multiroom subscribers.
The satellite giant has been a leading advocate of HD in the UK, and is keen that its multiroom subscribers can have a second HD option to complement a Sky+ HD box.
The box will come at no extra cost for new Sky Multiroom subscribers, although there is a �30 set-up charge for completely new customers and �60 for current subscribers extending their packages.
Google to do away with fuzzy YouTube videos with latest purchase
Shaky, blurry YouTube videos could be a thing of the past thanks to Google's latest company acquisition.
The search giant has picked up Green Parrot Pictures, an Irish digital video technology company, whose image processing tech has been used in Lord of the Rings, X-Men and Spider-Man in recent years ? but don't let that put you off.
Google will use Green Parrot's technology to tidy up low-quality video content uploaded to YouTube by sharpening images, reducing visual noise and producing a steadier video.

Cloud computing brought the browser wars back: Microsoft, Google and Mozilla have been rewriting JavaScript engines, improving their support for web standards and improving their user interfaces.
The result is the big three's best browsers yet: IE9, Chrome 10 and Firefox 4 RC. So which one deserves a place on your desktop?
10 best alternative operating systems
It might seem audacious to claim that the next Windows is cooking in some part-time coder's house, but it's nothing new. Microsoft's OS empire started with the purchase of QDOS, which stood for 'Quick and Dirty Operating System'. Apple didn't create Mac OS X out of thin air, but took an open source kernel and some BSD code (grounded in academia) to get the foundations of its operating system working.
The most successful projects often begin life in ways we'd never expect, and it can take a while for their potential to be fully realised.
We look at the best alternative operating systems, with the potential to change the computing landscape over the next decade. There's only one rule - no Microsoft, Apple or Linux.
10 best touchscreen phones for 2011
Swapping a button-bashing existence for a softer sensing interface we can press, swipe, pinch and zoom, means we can now do a little bit more than simply stare into that pint-sized screen of ours.
If the only QWERTY keyboard you want to see on a daily basis is the one nestled next to your office computer, here's our pick of the best touchscreen smartphones available right now in the UK
Motorola Atrix vs Samsung Galaxy S2 vs LG Optimus 3D
Two of the highlights of this year's Mobile World Congress were the powerful Samsung Galaxy S2 (Galaxy S II) and the futuristic LG Optimus 3D.
But how do they compare to the spec-heavy Motorola Atrix, announced at CES in January? All three are super smartphones with dual-core ARM processors as you'll see.
All three handsets also impress with cutting-edge screen technology, although they couldn't be more different in their execution.
So it's hard to measure whether the Atrix or Galaxy S2 is 'better' than the Optimus 3D . Or vice-versa. But you can get a good feel for which phone you fancy by comparing them side-by-side...
How iPad 3 can fulfil Apple's 'post-PC device' promise
A revolution is happening in the consumer technology world - the PC is slowly, but inexorably, being replaced by the tablet.
It doesn't seem to be a question of if a tablet can replace a conventional computer, but rather how long it'll be before PCs are in the minority in both the home and workplace.
Top five reviews
The Apple iPad 2 has arrived. It's the greatest tablet we've ever seen. It's slim, sexy and amazing. But is it really that different to the first iPad?
Canon's triple-digit EOS line has traditionally catered for those dipping their toes into DSLR photography, but successive models have been venturing further into enthusiast territory.
IE9 is a leap forward, and Microsoft has done a fine job. Some of the features in IE9 are genuinely innovative, and as it's well placed to usher in a richer web experience.
Canon has long catered well for the entry-level digital SLR market. Its EOS 300D was the first digital SLR available for under �1000 and as technology has advanced, its cameras aimed at this market have gotten cheaper and more compact, whilst still sporting a decent array of features.
The Motorola Xoom is the first Android 3.0 tablet to hit the market. That makes it the first Android tablet to ship with an OS that's designed especially for big screens, and that's why it's so exciting.
