On my BlackBerry Bold, I would get an email INSTANTLY. If I sent an email to myself (from my phone to my yahoo account, for example), the email would appear 100% right away. On the iPhone, that does not appear to be happening. Basically, emails on the BlackBerry came right away and without me having to actually push the 'email' button for it to refresh... Kind of like text messages do. How do I do this on my iPhone 4S? It's kind of annoying because I REALLY rely on email a lot, and I need for the phone to get emails right away and do it on it's on. I have all push notifications set to 'on', what else can I do?
