Yes but how selective is the iPhone email application? Will it download everything? Does it ignore attachments unless you ask for them?
It's pretty selective. Allows you to download attachements when you need them.

One other aspect is, that ALL of the traffic is covered by the flat rate, only the 500 FIRST MB will be delivered with 3G speed, everything higher than 500 MB only at ISDN speed. So there is no risk in cost explosion.
