The touchscreen Developer Preview version of forthcoming mobile operating system Ubuntu will be published on Thursday 21st February, enabling mobile developers with a Galaxy Nexus or Nexus 4 smartphone to run the new platform.

Canonical, the business team behind the Ubuntu project, will also be ‘flashing’ phones to Ubuntu at Mobile World Congress in Barcelona from 25th to 28th February.

Just over a week before Mobile World Congress 2013 begins in Barcelona, the GSMA has been involved in the opening of another MWC.

This is the Mobile World Centre - officially known as the Mobile World Centre Barcelona Espacio Movistar - and, unlike Mobile World Congress, it’s designed for consumers as well as for people working in the mobile communications industry.

LG Electronics says it’s sold over 15 million smartphones in its Optimus L Series since launching them at Mobile World Congress last year, with one device being sold somewhere in the world every second during the past two months.

There’s now an upgraded range being prepared for an official launch at MWC 2013: the Optimus L Series^II will comprise a number of devices with higher specifications than the original handsets and distinctive LED Lighting on the ‘home’ button.

Opera Software, best known for its PC and mobile web browsers, has acquired California-based rival Skyfire Labs.

Skyfire offers consumers a mobile browser that can handle Flash Video and a variety of other video formats. In addition, its ‘Rocket Optimizer’ software can be used by mobile operators to reduce the size of video and other multimedia material when mobile bandwidth is under demand.

Truphone is a pioneer of internet calling via WiFi - and it's recently announced a new service that aims to integrate GSM calls with its VoIP app.
