I recently visited Seoul, South Korea and was a bit surprised to learn before traveling that UK mobile phones would not work in this country. As an owner of an iPhone 3G i thought that it was bound to work, however on searching the internet there are some conflicting views about this (for/ against) since the iPhone 3G is not on sale in this market.

My experience - the iPhone 3G worked absolutely fine. It picks up a network and can make calls and send SMS’s no problem. I did not turn on data roaming as i’m sure this is expensive, however, since Seoul (and also Cheongju to an extent) is full of free public WiFi the iPhone actually works better here than it does in London. So if you want to use it to email/ upload photos, browse the net etc it works like a dream….
