Sprint Nextel inked a deal with cellular module provider u-blox to be Sprint's preferred module provider for its 2G (1xRTT) CDMA network. Sprint is seeking to cash in on the machine-to-machine market as AT&T Mobility and others shut down their 2G networks in the years ahead.

According to a new survey of all of the major North American wireless carriers, smartphones remain incredibly popular among subscribers, who are consuming an average of 694 MB per month in postpaid data.

But perhaps the most interesting finding from the PwC survey is that wireless carriers are seeing a dramatic 60 percent slowdown in the growth of traffic on their wireless networks.

Nokia reported a year-over-year and sequential drop in device sales in North America, but CEO Stephen Elop also hinted that the company will soon bring a "hero" Lumia Windows Phone smartphone to a top U.S. carrier, likely Verizon Wireless.
