New Nielsen studies on Friday showed that mobile data use was growing rapidly even as the cost of it was staying the same or going down. Mobile data use was up 89 percent on average in early 2011 from 230MB a month a year earlier to 435MB today. Since most data plans were either staying the same or dropping down in price due to caps, the price per megabyte had actually been cut almost in half, down 46 percent to eight cents.
