This morning is the last time my Gmail account worked on my Droid RAZR. Up to this point, it has worked fine and I can sign into my gmail account on my laptop so I know the password is correct, but it says: Connection error. The following error has prevented a successful connection: Incorrect username or password. Visit settings to correct. [NO Mechanism not available]. When I hit settings and add my password, it says: Attention. Invalid Credentials. Please help.
