Recent research released by analytics company Ericsson, shows that data traffic has now overtaken voice calls on mobile networks. In fact, data traffic is now double the bandwidth used by making phone calls. This surge is in part due to more PCs connecting through mobile data sticks, but it would seem that the largest surge is thanks to Facebook. Yup, with 100 million people regularly updating their FB status from their mobile, it would seem the networks are creeking under the strain.
