Why is my yahoo email not Pushing to my iPhone?

I have yahoo email and I know its supposed to " push " to your iphone once you get a email, but mine is not doing it. I have all the settings correct and everything, but sometimes it works and sometimes it dosent, and sometimes it takes 5 minutes after I get the email to push it to my iphone.





can anyone help? has this happened to anyone else?

before it didn't push my email but now of all of a sudden it works for me you can wait until the new iphone os 3.0 software is available this summer you can read about it at apple.com it is supposed to have a MUCH better push notification
