KDDI, Japan's number two cellphone carrier, totally blew our minds, everybody: they stated today that they'll be starting up an MVNO on Sprint in the US, name: KDDI Mobile. What's the point of yet another MVNO? (We're obligated to ask.) Well, besides giving Helio a run for their money in the Asian-carrier-gone-US-MVNO biz, maybe, just maybe we'll finally see a slew of totally slick and unbelievably well designed Japanese featurephones stateside (see above). Unfortunately, it sounds like they want to cater to Japanese expats in the US (are there really that many?); either way we definitely just got the warm n' fuzzies.
