I like your thinking, but this isn't entirely accurate. First off, CDMA requires whitelisting ESN's. A CDMA handset could be sold free and clear in the US, but Sprint and Verizon could simply refuse to allow the ESNs to be activated on their networks. Now you've got a lot of expensive bricks in your warehouse. AT&T and T-Mobile, on the other hand, could easily be used with unlocked units. But now you have a problem with the existing system where if Samsung just says, "hey, we're going to sell the GSII unlocked", now you have rubbed the biggest carrier in the country the wrong way. Good luck with future business. Yes, the smartphone is still up and coming, but Samsung sells a lot of basic and feature phones. A carrier like AT&T holds the threat of pulling ALL Samsung offerings which would hurt business. What you really need is a nationwide carrier that doesn't offer handsets, but rather SIM cards and subscription services on a BYOD basis. Here's the problem: what upstart can do this and provide nationwide service in a country that's bigger than all of Europe? There's a reason why it's easy to do this in other parts of the world. The countries are either A) the size of a US state, or B) the population is concentrated to certain areas (see China, Canada). The US is absolutely unique in its size combined with its population distribution. It has taken nearly a decade for Verizon to build out a nearly nationwide 3G network. While AT&T is nationwide, their HSPA network seriously pales in comparison to Verizon's. That's the sparsely colored blue map you see Verizon throwing up next to their near-blanket red one. AT&T's 98% coverage includes a lot of EDGE or GPRS-only coverage.
