Is anybody have luck with YMail Push. My ymail has only pushed mail to my iPhone a couple of times and only when I first go to the web site and have it check my mail. I have my YMail account to also check my work POP3 account but it never has worked, even when I know there are emails sitting on the email server ymail says there are no emails available. Email was one of the main reasons I upgraded to the iPhone. I've been working with Yahoo on this issue but they don't seem to have any answers.
