BT has put its weight behind O2's 4G rollout as the two firms put pen to paper and sign a ten year deal.

O2 came out poorly from the 4G spectrum auction at the beginning of the year, gaining the least amount of the valuable frequencies so its new partnership with BT will come as welcome relief.

The deal will see BT build a new high capacity transmission network to ensure O2 has the capacity it needs to support the increased data demand - thought to be up to 400 per cent - on the 4G network.

'Mind-blowingly aggressive'

We've already heard from O2 that its 4G rollout will be 'mind-blowingly aggressive' in comparison with its 3G rollout, and the additional infrastructure support is now has from BT will help make that claim a reality.

O2 reckons it will be able to offer "unrivalled mobile phone and internet browsing experiences" - something we're pretty sure EE, Vodafone and Three probably won't be in agreement with.

While EE has had a decent head start in the 4G arena take-up hasn't exactly exploded, leaving the door open for the other networks to claim a decent chunk of the LTE market when they come online later this year.

Google may not be prepping Android 5.0 Key Lime Pie for its annual IO conference next month with fresh reports suggesting Android 4.3 may be on the way instead.

The folks over at Android Police have apparently spotted some server logs which point towards Nexus 4 and Nexus 7 devices running an updated version of Jelly Bean - Android 4.3.

According to the report the IP addresses of the devices have be traced back to Google's offices and two separate employees, although we remain sceptical on that particular fact for the time being.

Delayed?

Last week we heard reports that Key Lime Pie wasn't going to appear at Google IO, as the search giant could be delaying its launch to allow manufacturers time to roll out Jelly Bean to their current crop of handsets.

This latest news jives pretty well with suggestions of a delayed Android 5.0 arrival and Google may be releasing a little Jelly Bean update in May to keep everyone sweet in the meantime.

Additional weight has been added to the Android 4.3 argument after a Reddit user did some snooping of their own, claiming to have found various pieces of evidence relating to the existence of Android 4.3.

These sort of details can be forged and while Android Police claims it's traced some of the information back to Google itself, we still can't be sure what we're going to see at Google IO in May.

In our tech-focused minds its sometimes easy to forget that not everyone is packing a cutting edge, top of the range smartphone in their jeans pocket or even wants one.

So when IDC announced on Friday that sales of smartphones had overtaken feature phones for the first time ever, our initial reaction was 'wait is that just happening now?'

Apparently so, according to the research company 51.6 per cent of the 418.6 million handsets shipped during the first three months of 2013 were smartphones.

The figures state that smartphone shipments went up a whopping 42 percent compared with the same period of 2012, bringing the figure to more than 216 million in total.

Samsung way on top

"Phone users want computers in their pockets. The days where phones are used primarily to make phone calls and send text messages are quickly fading away," wrote said Kevin Restivo, senior research analyst with IDC.

Naturally, it's Samsung who've driven the lion's share of the increase, with an incredible 32.7 per cent of all smartphone shipments during the quarter.

That's nearly double Apple's tally of 17.3 per cent during the same period, while LG was way back in third place, according to IDC's figures.

So now smartphones have finally taken the lead over their call-and-text happy low-spec rivals we can finally stop talking about the smartphone revolution. Which brings us to the next question.... What's next?

LG's Optimus F5 handset has been sitting tight since its unveiling at Mobile World Congress in February, but the company is finally ready to unleash it on the world, or at least parts of it.

The mid-range, LTE-enabled handset will arrive in France on April 29, the company announced in a press release this weekend, before heading around other unspecified parts of the continent.

The Android 4.1 device has a 4.3-inch IPS display, 1.2GHz dual-core processor, 5-megapixel camera, 8GB of internal storage, 1GB of RAM and a hefty 2150mAh battery

The handset is primarily aimed at new 4G LTE markets to enable those on smaller budgets to reap the benefits of faster speeds, without spending the earth on the handset.

US or UK on the launch list?

Following the French launch, LG says roll outs in Central America, Asia and South America will follow.

Whether a UK and US launch will also be on the agenda remains to be seen, but the Korean giant recently said it was hoping to re-enter the UK market with 4G-enabled phones with a quickness.

The Apple iMessage client for iPhone and Mac OS X is apparently experiencing a strange bug which omits the last word of a sentence when specific phrases are in use.

Oddly, any message involving President Barack Obama or the phrase 'The best prize is a surprise' will leave out the last word of the message for both the sender and recipient.

Instead of the word there'll be a series of spaces, however if users copy and paste the message rather than typing it, the message appears as it should.

Strangely enough, it seems the issue is not affecting the iMessage client for iPad users.

Series of issues

This isn't the first issue to plague the Apple-to-Apple messaging service in recent months. There have been a number of iCloud outages which have rendered the service useless for hours at a time.

Just last month we reported on an issue that saw certain iOS developers targetted by DDoS attacks that forced the iMessage app to crash.

Another security loophole allowed the entire iMessage archive to be accessed simply by placing the sim card in a different iPhone.

Earlier this month, on the other hand, one expert stated that iMessage was so secure that not even the authorities could decrypt messages.

This latest instance is certainly the least serious of those listed, but we can imagine leaving the last word off any message may alter the meaning of such texts. Especially those involving the president!
