Jobs and other Cupertino functionaries have apparently been flying to and fro in the hopes of securing a carrier for the iPhone in Japan. It sounds like NTT DoCoMo is their first choice, which is interesting as they don't really support a 2.5G network -- NTT DoCoMo's network is pretty much all 3G, so for the iPhone to work on their network, it would have to be 3G. Also apparently in the running is Japan's #3 carrier SoftBank Mobile, who also lacks a 2.5G network.
