Kantar also ranked U.S. mobile carriers by market share. No big surprises here. Verizon ( VZ) showed a nice gain, year-over-year, from 34.5% at the beginning of 2012 to 36.3% this year. AT&T ( T) grew slightly from 26.0% to 26.3%. Sprint/Nextel ( S) is now in third place with 13.1% of the current market up from 11.7%. The big loser among carriers was T-Mobile ( TMUS). Market share dropped from 14.8% in 2012 to 11.3% in the last quarter. Their numbers should improve with the recent addition of the iPhone 5 as well as their attractive, new pricing plans. Both AT&T and Verizon actually saw drops in iPhone sales compared to 2012. Android phones saw an good increase at AT&T while Windows Phones made huge gains at Verizon. --Written by Gary Krakow in New York. >To submit a news tip, send an email to: email@example.com.
