Android overtook iPhone in new sales for H1, but BlackBerry may be under pressure

Smartphones now account for 25% of all US mobile subscribers, according to The Nielsen Company. That's up from 16% a year ago.

What's more, Nielsen has predicted that smartphones will overtake feature phones in the US by the end of 2011. This is in terms of install base - not just new quarterly sales.

Nielsen has also broken down the share of all smartphones by OS, with RIM in the lead on 35%, followed by iPhone (28%), Windows Mobile (15%) and Android (13%). Android is rising fast, and looks set to overtake WinMo next quarter.

In fact, Nielsen says Android took a 27% share of new smartphones bought in the first half of this year in the US, behind only RIM's 33%, and ahead of iPhone's 23%.
