Google took to its Support site earlier this week to make an "end of life" announcement for its native Gmail BlackBerry App. BlackBerry users will now have to use the Gmail mobile web app if they would like to take advantage of new Gmail features on their device. 

Beginning November 22, 2011, we will end support for the Gmail App for Blackberry (installed native app). Over this past year, we've focused efforts on building a great Gmail experience in the mobile browser and will continue investing in this area.

Users may continue to use the app, if installed, however it will not be supported by Google, or available for download starting November 22. BlackBerry users can continue to access Gmail through the mobile web app at in their BlackBerry web browser.

It seems to us that Google has decided that the BlackBerry platform is no longer important enough to focus its efforts on. Last week, Google attempted to launch its native iOS 5 app, but quickly pulled it from the App Store after discovering a flaw. So, the company does not have an initiative to push all mobile users to its mobile web app—just the ones using a platform it believes to be dying.
