Japanese handphones conversion

I have a friend who bought 1 from Japan and had it converted to be usable here. Anyone heard of it before? Any details?

PDC, CDMA, or WCDMA? Laughing

wah. explain please.

Ask your friend, see what he reply. Laughing

japan has their own standard of HP...can convert meh?

3G phones can be used in Japan.

That's because japan utilises WCDMA, which is 3G. Laughing
