Based on your posts, you seem to be a networking l337, so I guess your real question is not about the technology itself, why sending e-mails over 3G on a Kindle will incur a charge and not on Wi-Fi, blah, blah, I can do this, etc.
Your real question is how Amazon implemented the process of sending/converting files, you should ask them why, unless someone from Amazon Kindle Management trolls around this forum, I doubt it if someone can answer a technical guy like you straight up.
But still the bottom line is 3G is provided by Telcos, and every time Amazon needs to send over something over 3G they will bill the user because AT&T will bill them, as previously explained by jswinden.
Sending files is not a common transaction compared to just browsing the web. Files to be sent over the air varies in size, bigger size means more bandwidth use. Compared to casual web browsing on web sites which usually produces a constant stream and amount of traffic, or even better, a fixed amount. This means a fixed amount of data over the air.
Amazon's Kindle platform is a "walled-garden", similar to Apple's iTunes and App Market that caters all things i-Device (iPhone, iPod, etc.) They have complete control of the platform and the environment.
Hope this helps, thanks.
