Yes, yes, i know... But i thought bringing UMTS, HSDPA and the rest of the alphabet soup into the argument would just obfuscate the point even more.
The point is - all 3G standards are CDMA (/WCDMA) based and "CDMA" by itself means nothing. It's not a standard, it's a method
Further point is - the standards and transmission methods are completely irrelevant to Kindle's model. It's the business / marketing model that makes it what it is, and that's simply not achievable in an international / multy-country / multi-carrier setting.
