Switzerland a beautiful country and a wonderful place to buy 3G iPhones. The Swiss carrier Swisscom offers the iPhone 3G with a prepaid SIM card. Forum reports confirm that foreigners can buy these aswell. Only two problems remain: first the Swisscom iPhone is completely sold out on Switzerland and second it is SIM locked to Swisscom (offical unlocked carrier list here). But as reported by us yesterday, a SIM proxy adapter unlock occurred in Vietnam. We expect this adapter to very soon hit the markets worldwide.
