One of the tricks I have used to get Yahoo Push Email to work again was to delete the oldest mail. Today I notice that along with about 5 new mails I had mail in the list that I had already deleted. Some were from about 4 days ago (I do not keep old mail on my iPhone). Once I deleted the old mail that I had already deleted before then Push started working again. Prior to that my iPhone was just setting there with "Checking for Mail". This would have to be a problem with Yahoo since I saw this on the Web Interface. If you notice this problem, please post here. Maybe this is one of the main reasons for Yahoo Push Email to stop working. Also, anybody got the new Yahoo Mail Web Interface? Mine is still on the Beta Version when I switch to the new email.
