they use different signals in japan, which are way different here. the wavelength or whatever that japanese phones use for tv is being used by the military in the states, and since japan is smaller and the nation is ruled by virtually two carriers, the systems and networks are easier to upgrade and take a shorter amount of time, unlike in america, where things take a horribly long time to get done, like t-mobile's 3G band, or any cell carriers introducing live videochat. if i got anything wrong, somebody far more knowledgable in this area correct me :]
Well, their 3G is technically compatible with at&t's 3G, just a different frequency (2100MHz), and already compatible with Europe's. The question is why is USA tech so gay?
At least I can take my Kaiser to Japan and use it there, depending on SIM availability.
2 things keep Japanese CDMA (the phones displayed on this page) phones from being used in the US. 1. Japanese 3G all runs on 2100MHz. Even the CDMA-EVDO, which no other CDMA country does. 2. Non-standard ESNs. Their CDMA ESNs run 5 letters and 6 digits (for example, an old phone of mine has the ESN of STSBT837195 with no decimal equivalent).
But do notice that Sony-Ericsson makes CDMA phones for Japan. They'd blow the competition out of the water if they re-entered the US CDMA market with phones like those.
The same reason we don't get the cool subnotebooks and PDAs anymore. Americans just don't want to spend much on technology unless their company is providing it for them.
Not a bad thing, but it definitely keeps us behind those who are willing to pony up.
