Thanks sparkchaser,
I've already got a small 3 pronged adapter for the UK like the one shown in the pictures from the Amazon site you've linked to, so that should work for us on our trip.
Thanks for all the replies. Just wasn't sure that my cellphone's wall charger would work in the UK without frying the phone, and that's why I might have needed a different converter or charger if it wouldn't work overseas. Who do I bill for a new phone if my phone starts smoking when I charge it in the UK? Just joking, thanks for all the help and tips.
