Hey guys, I will be going on holiday with my iPhone in a few weeks and obviously I want to take my iPhone with me and of course I don't want to run up any insane bills. What shall I enable/disable to make sure I do not run up any nasty bills? Data roaming is already set to off and I will turn off 3G before I go (just incase ) should I turn off location services? Is there anything else? Thank you!
