Going on a Mediterranean cruise and will be taking my iPhone 4 with; as well as an iPad. Dont want/need to use the iPhone 4 for phone communication. as I will probably purchase a cheap phone once over there. Wondering what is the safest way to tweak the iPhone and iPad so as not to incur any accidental or unexpected charges. I know that I can turn 3G of as well as Cellular Data and Roaming. Will this do the trick? Is removing the simm cards an option? Just dont want to return to Canada and discover that I have incurred some major charges from my phone provider!
