3G iPhone in Japan?

New reports have suggested that Apple is in talks with DoCoMo to bring the iPhone to Japan.

Tech.co.uk claims that this must mean a 3G iPhone is in the works as there is no EDGE network in Japan:

Wherever the iPhone ends up in Japan, it means one thing - it has to be a 3G model, as there simply is no GSM network in the country. Suggestions of a new model with a CDMA chip of some sort appearing late in 2008 suddenly seem so much more believable.
