My thoughts on the Verizon iPhone: To those who say that Verizon won't get the iPhone because they demand "too much control??" They are in the process of getting the Nexus One, a phone without VCast, sold directly by Google. If that's not getting over there control issues, I don't know what is.
As for the Verizon iPhone, Apple would be stupid not to tap into that market with the continued increase in smartphone desire by customers, couple with Verizon's steller network. As for the Voice + Data concerns, LTE is around the corner (which as far as I know lets you do both) so it would be smart for them to get in the door early to perfect the Verizon iPhone for when it's up and running.
PS -- To address the argument that it would be a "waste" to develop a CDMA chip when the capability is about to become outdated, I think it's a moot point. The fact of the matter is a lot of money can be made on the Verizon version in a short period of time (without a large capital investment) and the technology is changing so quickly anyway, in a year, they phone will be completely different as we've seen.
