I reluctantly switched my cell plan from Verizon to AT&T because almost all my family uses AT&T and we can talk for free, that is, until AT&T decides to do away with that option. I wish I had stayed with Verizon. Okay I know that was , but sort of related.

I think the reason why Amazon switched to AT&T was because they are the only national GSM cellular company in the US and it makes sense from their viewpoint to make a single model of Kindle with a GSM phone that can be used around the world rather than two models one with CDMA for US and one with GSM for the rest of the world.

An example of 3G impotence with AT&T: With my KDXG I tried to use 3G to download a 24MB file from my archive. Keep in mind that I live in the middle part of the huge metro area known as Dallas/Fort Worth and that AT&T is headquartered in my city about 9 miles away. There should be great 3G coverage, or so you would think. Nope, the 24MB file would never download via Whispernet. I've never been able to download even a small 300KB file in 60 seconds or less, though they do usually download eventually. When I got my K3 yesterday I immediately downloaded much of my archived library via WiFi Whispernet, including the above mentioned 24MB book, probably about 200MB and it only took a few minutes.
