Comscore: Android, Apple Cleaning Up In U.S. As RIM, Motorola Struggle

Android continues to gain strength in the U.S smartphone market ahead of the pending debut of the iPhone 5, according to the most recent numbers from Comscore (NSDQ: SCOR). And in another sign of the times, Research in Motion (NSDQ: RIMM) will be watching very closely to see if new BlackBerrys set to arrive over the next few weeks can arrest a market share swoon that continued in June.

When measured by operating system, the U.S. smartphone market exhibited much of the same patterns it has been showing all year. Android gained 5.4 percentage points of share, Apple (NSDQ: AAPL) continued to do well, and RIM continued to fall. Android now has 40.1 percent of the U.S. market, compared to 26.6 percent for Apple and 23.4 percent for RIM.

The big test for Android in the second half of the year will be the debut of the iPhone 5. Apple hasn’t updated the iPhone in over a year, but it continues to sell well against the dozens of Android handsets available in the U.S. market that have been released more recently. As for RIM, early reaction to the BlackBerry 7 models unveiled yesterday seems to underscore the fact that RIM really needs to get cracking on a QNX version of the BlackBerry before U.S. buyers consider it on par with Apple and Android.

Samsung continues to be the top vendor in the U.S. when it comes to overall sales of mobile devices, including both smartphones and feature phones. Apple was actually the fastest growing mobile device vendor over the last three months despite not having any low-cost feature phones in the market, although the $49 iPhone 3GS available through AT&T (NYSE: T) is a pretty good deal.

Motorola (NYSE: MMI) was the only major vendor to lose market share in the U.S. during the last three months, which makes sense in light of its lackluster earnings report last week.
