About one in 10 mobile phone subscribers in the United States is now using an Apple iPhone, said a new survey released on Friday.

Latest survey results from research firm comScore showed that for the three-month period ending in October, Apple remained the No. 4 handset maker in the U.S. with its share of mobile subscribers rising to 10.8 percent from 9.5 percent in the previous three months.

Among the top five mobile phone brands in the U.S. market, Apple is the only one that saw its market share increase in the quarter, according to the survey.

Samsung was still the top handset manufacturer with 25.5 percent of U.S. mobile subscribers, followed by LG and Motorola taking the second and third place with 20.6 percent and 13.6 percent of share respectively.

Research in Motion (RIM), maker of Blackberry, ranked No. 5 with a share of 6.6 percent.

Except Apple, market shares of the other four brands remained unchanged or dropped from the previous quarter.

Apple's gain in the quarter might be driven by the introduction of new model iPhone 4S which went on sale on Oct. 14, and the addition of Sprint as a carrier in the U.S. market, some analysts said.

The survey by comScore, which involved more than 30,000 U.S. mobile subscribers, found that 234 million Americans age 13 and older used mobile devices by the end of October.
