If you didn’t get around to updating your Android device to the latest version of Gmail and are wondering why it isn’t showing in the Android Market, you may or may not be relieved to know Google has pulled the update after many users have reported stability issues.
If you did get the update and are experiencing problems, Google recommends going into your application setting and uninstalling updates to your Gmail app. The problem arrises if you had previously been using a 2.2 build of Gmail before upgrading. Upgrading from a 2.3.x version should be safe.
Expect a new version of the app in the market soon.
