You don't need to remove one of the apps. You just need to remove the account from one of the apps.I am tired of receiving double email notices every time I get an email. I have two email apps: Google and Mail. Both came with my phone and neither can be removed from the manage app dialogs.
Don't rely on memory. Verify. Go into the email app, access the menu and go to the accounts screen. If your gmail account is listed there then remove it.I don't think so. I'm pretty sure the phone came that way
