I have a Yahoo e-mail account, an AOL account and a Gmail account. My iPhone has no problem pulling the Gmail and AOL mail based on the frequency I set in preferences, but the Yahoo mail will only come over when I open the inbox and click the connect button. I went to Apple service, and they said that this is a Yahoo mail problem, as evidenced by the fact that the other two accounts work fine.Most of my mail is on Yahoo and I would prefer not to change that, but this is a very cumbersome way to get the mail and it means I get no notifications of new mail. Is this something Yahoo is working on? Alternatively, is there anything I can change in my setup that will make it work better? If so, please provide non-technical instructions.Thank you.
