Automatic retrieval of e-mails

[kAoTiX]

Am I being stupid or have I just missed something?
I want to receive e-mails automatically on my iPhone 3G by checking every 30 mins or so. Preferably by 3G as I obviously don't have a wifi connection all the time.

I've looked in the settings and couldn't really find anything to do this so if anyone can help i'd really appreciate it.
As a side note I can understand requesting e-mails all the time can consume alot of data but I have an unlimited data plan so it isn't an issue at all.

Thanks

Be warned: Fetch, when I used it, went thru my battery like a fat kid thru a jelly donut. I've turned it off for now, waiting for "true" Push to be implemented. I just hit connect when I want to check my mail.

Well thanks for the reply, i didn't see that option initially. And thanks for the heads up about fat kids and jelly donuts, i'll try it out for a week or so and if my battery life is impacted i'll probably have to turn it off.
