Analytics firm ComScore just released a new batch of numbers, showing Android extending its lead over, well, everybody in the United States for September through November of 2011.

Out of the 91.4 million smartphone subscribers in the United States, ComScore says 46.9 percent — about 43 million give or take — have Android smartphones. That’s up 3.1 percentage points from the June through August. Apple, meanwhile, saw slower growth, at 28.7 percent (up from 27.3 percent for the previous period).

Those were only platforms to see growth — RIM was down 3.1 percentage points to 16.6 percent, microsft fell a half-percentage point to 5.2 percent, and Symbian down three-tenths of a percentage point to 1.5 percent. WebOS was a no-show.
