the iPhone runs on GSM 850, GSM 900, GSM 1800, GSM 1900. what frequencies do you think the 3g iPhone would run on? vodafone new zealand has 2100mhz and 900mhz umts. Some countries use umts 850 mhz and at&t that has the iPhone in the usa uses umts 1900 mhz.
so for the iPhone 3g version to work around the world it would have to be umts 850,900,1900,2100mhz
