R.I.P. voice and texting: these two bastions of mobile revenue are set to be usurped by rich social media fuelled by an increasingly ubiquitous mobile web. Speaking in a keynote at the Symbian Smartphone Show in London John Ellis, director of carrier market development in Motorola's software ecosystem team, said: "Texting and voice of today are slowly evaporating and slowly diminishing in our rear view mirror as we move into social media, rich user experiences."

Ellis predicted within five years smart phones will be poised to outsell basic mobiles in global sales – rising from nine per cent of the global mobile market today to 23 per cent in 2012, while basic mobiles will see their market share diminish from 34 per cent today to 24 per cent over the same period.

"Feature phones of tomorrow are smart phones of today. Convergence is happening. And what's really nice about this is that this convergence does not displace technologies – rather, it expands the mobile opportunity."
