Samsung Galaxy S4 a no-show at Mobile World Congress - 2013

The Galaxy S3 launch event last year in the U.K.

Samsung Electronics wants the spotlight all to itself for the Galaxy S4.

The Korean electronics giant will be holding off on any major announcements at Mobile World Congress later this month, according to a person familiar with its launch plans. As with last year, Samsung will likely hold its own separate event to launch the latest iteration of its flagship Galaxy S franchise.

We're not sure exactly how many major new phones will launch at the show this year, with Samsung, HTC and Apple all saving their flagships for separate events.

But we're really excited to see what Nokia's got up its sleeve, and we're expecting a slew of handsets from the likes of LG, Huawei, ZTE and Acer.

Tablet time

Not forgetting tablets, of course, which we reckon Samsung and Asus are likely to focus on at the show.

And in between the two, we have no doubt that 'phablet' will be one of this year's biggest buzzwords - perhaps we'll get the answer to that age old question: at what size does a 'phablet' become a tablet?

The coverage kicks off on Sunday and we'll be bringing you all the news and the most comprehensive hands on reviews of the new gizmos all the way through the week.

So sit back, relax and join us - we'll be updating this page to keep you posted on what's what, as well as tweeting and Facebooking throughout.

The issue comes down to the general tendency for technology companies to be run by engineers with no IT experience and therefore no real clue about what a business IT organization-including their own-actually does.

IT, when done right, is largely transparent. As a result, it's often taken for granted. This makes it hard to build products for IT without engaging IT and hiring people with significant IT experience to work on the effort.

BlackBerry: Keeping IT in Mind From the Beginning

BlackBerry started with businesses as its primary customers. Then known as Research in Motion, the company initially brought the two-way pager into the mainstream-and, unlike today's typical smartphones and tablets, these actually entered the market as executive tools, not consumer products. From the very start, the company had to learn what IT needed and how to protect top executives. These were lessons hard learned.

Look at BlackBerry security efforts, then, and you see that they start and end with targeted IT needs. BlackBerry ties its systems into IT policy, assuring that IT can easily get the devices to conform. This is critical; IT doesn't have the time to manage everything that's currently on the table, and BlackBerry is designed to assure compliance without significantly increasing IT overhead.

One of the most talked-about problems since the introduction of the smartphone is separating personal and corporate information. This is because IT doesn't want to deal with personal apps and files, and users don't want IT seeing their personal stuff.

BlackBerry separates the environments on its devices, giving the user his own space and letting IT manage and secure the business information under its control. This is unique in the market-and it was driven by IT demands for this feature.

When developing its unique tablet, the BlackBerry PlayBook, the company tied it to its overall security framework and sandboxed the apps so they can't do hostile things. Looking at the overall nature of email and application attacks, BlackBerry created permissions and monitoring components that directly address the damage these attacks can cause, even though BlackBerry platform is generally less likely to be attacked than one of the consumer platforms.

Samsung: Start With an Insecure Platform, Bolt on Security

Samsung, in contrast, created SAFE. The company started with Android, the only platform actively being blocked by IT organizations due to security concerns. I was at an event last year where McAfee showcased that an Android phone can be remotely attacked, put into a loop, overheat and catastrophically fail.
