Nielsen today released data that said that Google Android equipped phones outsold Apple iOS devices by 27 percent to 23 percent for the first half of 2010. This goes along with the recent data by the NPD, which said that Android outsold iPhone by 28 percent to 21 percent.

The iPhone 4 only did go on sale during the final week of the first half, so its launch isn’t fully reflected in the results. Still, the Android is available for more carriers at the moment, though that could be affected if the iPhone switches over to another carrier in the near future.
