Since yesterday, I get the message 'User Name or PW for @gmail.com' is incorrect on the iPad only. Laptop and desktop work perfectly. Same for my other email accounts, including Yahoo. I've logged in and out of gmail.com on both the iPad and laptop. Also, I went to the email pref on the iPad, turned it off, and back on, all to no avail. One thing I've changed is upgrade to Snow Leopard yesterday pm. But again, all of my other accounts work as usual, and I can have access to gmail.com through the web site. Suggestions, Thks for your help.
