Apple Android GrowingAccording to data from comScore, iOS marketshare grew at a faster rate in the U.S. during the February to May period. However, of the 30,000 owners surveyed, Android accounted for just over half of U.S. smartphone subscribers, sitting at 50.9 percent.

Smartphone ownership was boosted up to 110 million consumers in the U.S. during the three months comScore collected data. During that period, Apple's iOS grew from 30.2 percent to 31.9. Android, on the other hand, went up .8 percentage points from February to May. Further down the pecking order was RIM at 11.4 percent in May, down from 13.4 percent in February, while Microsoft went up a percentage point to 4.0.

There were quite a few big name Android devices introduced recently, so we'd expect Android's adoption to go up quite a bit now that the One X and Galaxy S III are out in the wild. Conversely, we don't expect the iPhone's share to increase much — although the iPhone 4S is available in the prepaid market (here and here)— since a new device out of Cupertino isn't expected until October.
