What is this"push" you all talk about. Gmail doesn't have it yahoo does. What's the difference between fetch and push. I have an gmail account and a yahoo account I don't seem to notice any difference. What does push do? I need to be enlightened.
There is lots of info on this, on this forum.
But, simply put:
Fetch - your iPhone checks your account every X minutes for new data
PUSH - as soon as new data hits your account, whether it be email etc, it's delivered to your iPhone.
Downside to PUSH, is battery life. Since it's an open tunnell, 24/7/365 (unless you turn PUSH off, or the iPhone off)...
I guess I should have elaborated a little more (so you wouldn't have deleted my post - nice)...Actually push gives you better battery life. As an email is PUSHED to you when one arrives where as fetch is constantly polling - depending on the interval you choose - even if there is no email to grab.
Although this can differ depending on the amount of email you receive during your day. So in all honesty it depends.

It does depend greatly. Push notifications coupled with a fetch IMAP (Gmail) offers the best battery life setup w/out the loss of instant notification imho. That is why I mentioned PushMail. I have no affiliation with anyone or anything - I just know what works. Give it a shot, you will be pleasantly surprised. Battery life is at a premium on all iPhones, so this is pertinent and deserving of not being deleted.
