I installed K9 to view my GMail account. Now I need to remove my Gmail account from the Android built-in GMail app. (this is to avoid having 2 apps. for the same e-mail accouont, which in turn causes confusion on the notification settings). In the GMail app. there is no option to remove the account. Also, you can't remove the GMail app because it's part of Android 2.3.3.
