I have an iPhone 4S with Canadian provider, Rogers. This summer, I'm going to be covering the London 2012 Olympics for about a month. Rogers' rates (even with packages) are pretty insane for Europe. I decided that I'd come here to ask my fellow frequent travelers what to do... I really want to use my iPhone, so is it possible to switch the SIM card to a UK provider? If not - what would be the best method for getting an iPhone to use in the UK? Any advice is appreciated!
