Nokia is set to add the Lumia 1520 and 2520 models to its business trial scheme. The scheme, open to IT decision makers in the UK, gives organisations the chance to test a variety of Nokia handsets for 30 days.

Businesses can apply to trial the phones on the Nokia website. Those that qualify will currently receive a Nokia Lumia 520, 625 and 925 to test. Along with the phones, testers receive a built-in video player on which a preloaded video provides an introduction to the scheme, a variety of peripherals and tools for converting SIM cards to microSIM size and vice-versa.

Progressing in B2B

Talking to Mobile Magazine, Nokia Director of Business Sales for UK and Europe Adrian Williams said, "We have made good progress in 2013 and we now plan to scale our activities across all channels."

Nokia's share of the B2B market reportedly grew from 5 per cent in 2012 Q3 to 12 per cent in 2013 Q3. Williams explained whilst this is in part due to BlackBerry's poor performance, a dynamic market and Nokia's use of the Microsoft operating system were also both factors in its recent success.

"BlackBerry's situation does not change the fact that in the current economic climate all businesses are regularly considering their mobile strategy based on the need for best cost operation," he said. "For Nokia, having products that natively support the vast majority of company IT infrastructures this presents an accelerated opportunity, not to mention a more cost effective and simple upgrade path for our customers."

Williams also reportedly discussed a shift in focus for Nokia away from large businesses and towards SME and smaller organisations: "The smaller businesses represent the largest opportunity in the UK market and this is where we will be placing much more focus, to build awareness and demand. We have some very focused initiatives to engage with these customers."

Unable to be kept quiet before a possible MWC 2014 launch, more specifications of the upcoming HTC M8 have made their way onto the worldwide web.

A User Agent Profile (UAprof), highlighted by Twitter tipster @evleaks, reveals the upcoming HTC flagship will ship with a full HD 1920 x 1080 screen, as well as the latest version of Android.

This latest leak appears to confirm that the HTC M8 may already lag behind the impending Samsung Galaxy S5, a handset that is heavily rumoured to launch with a 2K display.

It makes Sense

This all corroborates with previous leaks, with an AnTuTu benchmark showing off the M8 running Android KitKat on a 5-inch Full HD display, as well as a previous evleaks tweet.

HTC is highly expected to customise the M8 with its all new Sense 6.0 UI, bringing over an improved version of BlinkFeed.

We've been waiting and waiting for a Tizen phone to emerge and finally we may get one at MWC 2014, but perhaps not from the source we were expecting.

Samsung is a major player in the Tizen project and the Korean firm has been heavily linked with smartphones running the alternative software for a while, but it could be beaten to the punch by Chinese manufacturer ZTE.

On the official Tizen website, details of its presence at MWC 2014 include a mention of a "ZTE Geek demo."

Going Geek

The ZTE Geek launched as a middle of the road Android 4.3 Jelly Bean smartphone in April 2013, but it could be able to make a comeback with an all new OS on board.

Questions are being raised over Tizen's appeal however, after Japanese network NTT DoCoMo opted not to range a Tizen handset due to its small market.

TechRadar will be at the Barcelona show to bring you all the latest mobile news, included developments in the Tizen arena.

• You can already find Tizen in a fridge and in a camera

As the launch of the Samsung Galaxy S5 edges closer, more specs are making their way onto the web. Unfortunately, that eye-scanner that we keep hearing about looks to have been omitted from the upcoming flagship, or has it?

According to industry sources talking to the Korea Herald "the tech giant will go for fingerprint authentication rather than unintuitive user experience of iris recognition".

This is in part due to a necessary redesign of the Galaxy S range, as well a current need to hold the phone to your eye in order to have it accurately scanned.

"Since iris recognition requires a long range camera, the smartphone, if fitted with the camera, needs a completely different design from previous models" said the unnamed source.

Now you see me..?

All is not lost for the eye-scanning tech though, with a tip passed to Phone Arena claiming that the Galaxy S5 will come with a refreshed design and a retina scanner - leaving us scratching our heads as to who is right.

Given that one of the biggest gripes with the Galaxy S4 was that it was so close in design to the Galaxy S3, an all new look for the S5 will be well received, yet Samsung will apparently stick to an all plastic construction.

The same leak also claims that the Galaxy S5 will come with that 2K QHD screen (1440 x 2560 pixels) we keep hearing about, as well as a 2900mAh battery. Could this be the fast-charging power pack that we heard about last week?

A 20MP camera has also been touted, contradicting rumours of a 16MP lens and putting it in the same league as the 20.7MP Sony Xperia Z1. It will record in 4K (like the Note 3) as well as simultaneously snap photos.

Given that all previous leaks have pointed towards a 16MP sensor, we'd advise taking this with a smidgeon of salt, and as far as eye scanners go, your guess is as good as ours.

• Hey, did you hear that Samsung is also refreshing the design of the UI?

It's that time of year where Samsung Galaxy S5 rumours are flying in thick and fast, and further leaks point towards a new user interface (UI) and "multi-hovering" controls.

First up is a screen leak from @evleaks - a usually reliable source of mobile slips - revealing a potentially revamped homescreen with large, Windows Phone-esque tiles with information you'd commonly find in the Google Now.

This isn't the first time we've seen screens along this theme, with the same Twitter leaker revealing some similar shots earlier this year.

It also resembles the design of the Magazine UI found on the new Galaxy Tab Pro tablets - although function appears to be different for the smartphone version.

The Samsung Galaxy S5 is expected to be the next flagship device to make its way out of the South Korean firm, and this new TouchWiz UI is tipped to feature on the handset.

Touch is so last year

That's not the only Samsung/Galaxy S5 related leak we have for your though, oh no, there's word from ETNews that the smartphone with take its Air View to the next level with multi-hovering.

A Samsung insider for the Korean publication claims the Galaxy S5 will off enhanced touch-free gestures, allowing users to hover not one, but two fingers above the screen to perform various tasks, with the system also boasting greater accuracy.

We weren't overly impressed with the Air View on the Galaxy S4, so unless Samsung has totally reinvented the system we're not getting particularly excited about this potential feature.
