Hi, I'm new to the forum and I tried searching on this but I couldn't really find the answer. I will be traveling to London, Paris and Germany and I have the Ipad 3G/WIFI. I know that if I want to use the 3G I would have to buy an International Data Plan and I don't want to do that. But if I find free WIFI (like in the hotel) and use that are there any additional charges or is it really free? Thanks for you help!
