It is also fun to see what cellphones are used in different countries. As my plane taxi into the Hong Kong airport, I looked over across the aisle and the occupant pulls out an iPhone, switched it on and proceed to check the weather. I had to ask -- Your iPhone works in Hong Kong? He replied "sure, just get it unlocked". He is not even a techie. While we are waiting to get off the plane, he further commented -- it's the same price here and in the States, buy one here, or get one unlocked at MongKok for USD 700-800, it will only take a few minutes, he said. That's about USD 100. The iPhone is a quad band phone for a reason!
