I live in the UK and im on holiday in America. I set my data roaming to the off position but it seems you cant connect to wifi when its like this (even though it see's the wireless signal). So ive set data roaming to on and it works I just have to hope I don't lose the wifi signal and it go onto 3g cause my bill would be massive!
