I have a problem with Nokia N900 setting. I got a pop-up displaying “user-name or password is in correct” and display to edit my imap4 setting whenever I get connect with my wifi but with e-mail I have no problems when I am connect to the y-mobile data service. I setup my e-mail through the e-mail setting on the main menu and I have e-mail with hotmail and gmail but its works fine on both the data plan. Does anyone help me out . Please help.
