My phone doesn't have the appropriate certificate.
You may be getting this error message: "Sorry, the Gmail mobile app will not work on your phone. Your phone doesn't have the appropriate certificate to communicate with Gmail. Try accessing Gmail on your mobile browser at http://m.gmail.com" The Gmail application requires a secure connection in order to connect to the Gmail server. There is a mismatch between the Gmail certificates on the server, and those provided by your phone's manufacturer. You can try using the xhtml interface to Gmail by typing http://m.gmail.com in your phone's browser; sometimes the certificates used by the browser are different from those available to Java applications.
