Safari's share of the mobile browser market grew from 55% in February to just shy of 62% last month, according to the latest stats from Netmarketshare (via AllThingD).
Note that although the company uses the term 'market share', it's actually measuring something quite different: traffic. iOS users do more mobile browsing than Android users, likely due to the dominance of the iPad in the tablet sector, so sites see more traffic from Safari users despite a true market share that will be substantially smaller.
