When I fly, I always turn the "Airplane mode to on", as I like to read while flying. Problem is when I get to my destination, I turn the airplane mode to off, but always have problems with my mail. When I join a network, internet is up and running, I get the following message "Cannot get mail. The user name or password for Gmail is incorrect" Now I have never changed anything and is really difficult to get this working. Does anyone have any ideas as to what is going on?
