So, I'm heading to London and Bath for 10 days next week. I actually have a UK cell phone that I will be taking with me for use while I am there, but I will also be bringing my iPhone, mainly to be using it as an iPod and for some Wifi internet. My carrier is Bell/Aliant (Canadian). I'm wondering what I need to do to keep it from charging me a fortune from roaming charges and all that; and whether or not use of the 3G network over there will burn me bigtime. Is there any way to just keep it from connecting to other networks so that I don't get charged anything while I use it for music etc.? Or am I completely retarded? Someone please fill me in!
