Android and Apple together now share for nearly 70% of smartphone subscribers in the U.S., according to new estimates for July by comScore, TechCrunch reports.

Android phones command nearly 42 % market share, while Apple’s iPhone captured 27 percent. Android is growing faster, up 5.4% from April and up 1.7 % from June.

The two smartphone powers keep taking share from RIM’s Blackberry, Microsoft, and Symbian. Blackberry took the biggest hit, down 4 points since April, 2011 to 21.7 %. Microsoft’s mobile OS share is down 1 % to 5.7 % of U.S. smartphone subscribers. And Symbian is barely hanging onto 1.9 % share in the U.S.

In terms of how people are using their smartphones, text messaging still tops the activities with 70 % of subscribers stating that they use their phones to text.

Browsing and downloading apps come in next with about 41% of users doing those activities, which kind of makes you wonder what the other 60 % are doing with their smartphones.
