To be honest, this is not really a surprise. If you buy a phone with the expectation of using the 3G feature extensively, you've probably done a little bit of research into whether or not you'll get a good reception in the places where you spend your time.
Living in Northern Ireland, I had no expectation of any (let alone a good) 3G connection - regardless of which operator I went with - anywhere except the centre of Belfast. Seems that Orange go a little further than that, but I usually just keep 3G turned off. This might mean I miss out on some of the better features of my iPhone (although it does increase battery life a little!), but to be honest I'm in range of a WiFi connection more often than I am of a 3G connection. For the other times, EDGE suffices.
