A new forecast from Informa Telecoms & Media expects mobile operators to increase their share of app revenues from 10% last year to 17% in 2016. However, they’ll also see their share of mobile content and commerce revenue drop from 44% in 2011 to 31% in 2016.

Although many services including mobile entertainment and messaging are going ‘over the top’, avoiding direct payments to networks, the adoption of carrier billing for paid app downloads will help to offset this lost revenue.

A new study from iGR predicts that amount of mobile data traffic worldwide will reach 7 million terabytes per month by 2016; a figure that’s 16 times bigger than last year’s mobile data usage. Global mobile data traffic in 2011 averaged 433,000 terabytes per month.

The figures include all mobile data networks, including 3G and 4G LTE, but exclude any WiFi traffic that’s been offloaded by mobile networks.

The ‘Google Glass’ wearable mobile computing device will be available to buy early next year - but only to US-based mobile developers. Developers who attended Google’s I/O conference this week have been invited to pre-order the headset, which is expected to sell for $1,500.

Sergey Brin, Google’s CEO, made the announcement today after a Google Glass demonstration that showcased the display and video camera capabilities of the prototype device.

The Google I/O developer conference has seen the company make a number of major announcements today. It’s confirmed the next version of its Android mobile operating system, it’s expanding the Google Play application store and it’s launching two new Nexus-branded devices.

More than 400 million Android devices have now been activated, with an average of twelve new Android devices now activated every every second.

Telecoms regulator Ofcom has published details of the complaints it’s received during the first three months of this year. It’s the fifth edition of quarterly data from the regulator; the current publication includes statistics about mobile phone, fixed-line telephone, fixed broadband and Pay TV providers.

As in previous quarters, mobile telephony generates a lower level of complaints than fixed-line voice and broadband services.
