Well I can still choose push on my iPhone, however it hasn't been pushing lately. I'm actually using an @att.net account, but it runs through yahoo.It has been my understanding that you have to upgrade your Yahoo account to the Yahoo Mail Plus ($19.99/yr) to take advantage of pop.
Figured I'd add my voice to the chorus: Yahoo Mail and GMail aren't pushing to the iPad.Is anyone using Yahoo not having the option to have their mail push?
