ChangeWave’s (http://www.changewave.com) latest corporate spending survey shows that the big winner in the business smart phone market this quarter is the Google Android Operating System, though Apple’s iOS still remains strong.

When the research group asked respondents which mobile operating system their company currently provides, the Android OS (16%) was the clear momentum winner, registering a six point jump in market share since a previous survey in May.

All told, over the past nine months the Android OS has seen a five-fold increase in corporate market share. At the same time, Research In Motion’s OS still holds the dominant share of the corporate market, but it has dropped three points since May in terms of current share. The Apple iOS remains strong, ticking higher by one point.

Going forward, 35% of respondents report their company plans to buy smart phones next quarter one point less than previously.
