Overall, a surveyed over 30,000 U.S. mobile subscribers age 13 and older found that an average of 234 million Americans used mobile devices during the third quarter.
Market leader worldwide No. 2 Samsung was the only other handset maker that didn't lose subscribers during the three month period, holding its 25.3% share with no change. LG and Motorola both showed a 0.7% decrease in subscribers, followed by RIM who shed 0.8% of the market.
The number of smartphone users rose 12% from the previous quarter with mobile platforms fighting for their share of 87.4 million subscribers.
