If Android Gingerbread Will be Available Q4 2010, Froyo's Release Might Be Soon (June or July)

Google has provided significant and frequent incremental updates for their Android mobile platform.

1.0 October 2008
1.5 April 2009
1.6 September 2009
2.0 November 2009
2.1 February 2010

Google didn’t provide a release date for 2.2 (Froyo). But, based on this information about the release that follows 2.2, I wouldn’t be surprised if Android OS 2.2’s beta period is very short.

Android 3.0 “Gingerbread” coming in Q4 2010, says WebM media team (EuroDroid)

Android Gingerbread is ‘planned for Q4 2010’

My guess is that Froyo will become available for handsets around the same time as iPhone OS 4.0: Late June or Early July.
