I have searched everywhere, but i cannot seem to find a definitive answer to my question. I have an iPhone 4 running iOS 5.0.1 and I am travelling from the UK to Spain for a week on the 3rd of July. My question is, how can i turn off all of the internet data that my phone uses, such as email etc. whilst still being able to make phone calls and receive SMS & MMS messages? I am thinking that the best way would probably be to restore my phone to factory settings just before I go and not set anything up apart from be able to make phone calls and receive messages. Would this method work? Thanks in advance to anyone who can help.
