If I remember correctly from MWSF, each iPhone was to come with a free Yahoo push email account but I haven't heard any mention of that since January. Is it still a planned feature? For my Treo I have my .mac and business mail forwarded to fastmail accounts which uses a specific IMAP protocol to push my email to me. It's a real battery saver and I'm hoping the iphone will still be able to accept pushed emails in this method. I also setup my treo so that when I send a message it looks like I'm sending it from my .mac account rather than the fastmail account which is actually on the treo.
