Sony Ericsson is busy at this year's Mobile World Congress revealing new handsets, along with the rest of the world's manufacturers.

But it's also taken the opportunity to reveal a new application concept called Creations, which despite still being a little vague, looks to be a step forward in reaching out to the modern mobile user.

"Co-creation focuses on facilitating the evolving needs of consumers, content publishers and developers, creating a community and a movement where they come together to personalise, share and continuously evolve and co-create mobile content," goes Sony Ericsson's pitch to the MWC.

Essentially this appears to be something of a Facebook type of community network, built within Sony Ericsson's ecosystem of handsets (thought it'll apparently be accessible through computers, too).

"Content will no longer be static as Creations allows content creators to produce content on the move from their mobile phone."

Users will be invited to create and share content, with developers and publishers providing applications to enhance and evolve the framework.

It's still a bit hard to figure out exactly what shape it'll take, but Sony Ericsson's promised us a "Creation Day" at MWC to expand on how Creations will work.
