Google released a statement yesterday indicating the end of support for the Gmail mobile application on the Blackberry platform. From the article:

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 http://www.gmail.com in their BlackBerry web browser.

If you want to run the Gmail mobile app on your Blackberry phone you should download it now. After November 22nd it will no longer be available. Once the support window expires there is no longer any guarantee that it will continue to work long term. There could be a day in which the Gmail service is tweaked and the mobile app stops working completely.

If you are checking e-mail on your Blackberry you should consider switching to the mobile web application sooner rather than later. It’s always better to plan for the conversion now than to be forced to do it later when the app eventually breaks. If your Blackberry has to be wiped because of a support issue after November 22nd you will have to immediately start using the mobile web application.
