can i manage the email downloads to save costs?

hi friends,

i've tried to search but am unable to come up to an answer for this - any help appreciated.

I use my blackberry 8900 for business and personal use - holds all my email / contacts / notes etc. I'm using a Mac so the iphone will be able to perform the same functions more or less. Push email can be done with Mobileme.

But i travel a lot and get close to 150 -200 emails per day many of them with attachments. With blackberry, the initial download per email is a few kb - then u have the option whether to download more. That's a huge saving on overseas data bills. But from what i've been reading, iphone downloads the entire message whether u like it or not..

Is my information correct? Is there any paid or unpaid application that can help me control this so that i download only a few kb per message WHEN I'M ROAMING...?

Can anybody who is using his iphone for business please give his experience with roaming costs ...

I called Apple and they said it was absolutely not possible to work around this - iphone will download the entire message. But i think a lot of people who use iphone, travel for business. Are they all on unlimited roaming data plans? Or do they all wait for wifi to download emails ... i think i'm probably missing something here.

Thanks for the help.

the iphone downloads the entire email but does it in a fraction of the time of the blackberry.

Download speeds are fantastic with Blackberry Bold (since it has a fast processor) - but again, insofar as email is concerned, Blackberry only downloads a few kb per email as compared to the iphone (which downloads the complete html message). So i guess u're right there.

But my question still remains about controlling the amount of kb per email downloaded.

Thx.
