Kindle is getting some absurd deal on international wireless data?

Update: Whoops – I didn’t read the fine, fine print.  It is $1.99/item extra to download internationally. -Thanks Commenter

We found out last night that Amazon’s Kindle will now be riding on the same network as the iPhone in the US –at least the international version will be.  The question we immediately have to ask is: How does AT&T provide that data to Amazon at basically the same rate as Sprint’s domestic service?!  The only additional charge is a $20 up-front cost which is the difference in the price between the $259 Sprint model and the $279 AT&T international version.

Even if Amazon floats some money to the wireless carriers for each item purchased on the Kindle, how can AT&T get basically the same cut as Sprint, yet deliver international data packets?

Have you seen international data rates lately?  That $20 would get eaten up with the first 20 MBs of international data.  After that, who pays the international rate difference?  Can anyone hazard a guess how AT&T is allowing the Kindle to get data at domestic rates when all of us iPhone users are paying at least $25 for 20MB of data? 

Also: Will AT&T offer that same data plan, or lack thereof, to Apple’s tablet (though admittedly it will use much more data)?

 For your reference, here is AT&T’s International phone rates:

$24.99/month: 20 MB Data Global Add-On gives you 20 MB of usage within over 90 countries
$59.99/month: 50 MB Data Global Add-On gives you 50 MB of usage within over 90 countries
$119.99/month: 100 MB Data Global Add-On gives you 100 MB of usage within over 90 countries
$199.99/month: 200 MB Data Global Add-On gives you 200 MB of usage within over 90 countries
