My understanding is that the G1 is a dual band 3G phone. It uses UMTS band IV for 3G in the US and UMTS band I elsewhere. Europe uses UMTS band I as do Japan and Korea. The only hardware differences between the US and European G1 are cosmetic. Any unlocked G1 should be capable of operating on a 3G network in the US, Europe, Japan, and South Korea. A quick google search appears to confirm that people have successfully used their G1s in Japan and South Korea
