I have an iPhone 4S. I bought it unlocked from Apple's Canadian website. I'm hoping to go to Europe for a few months early next year, and I'm curious what the difference between the iPhone 4S and 5 would be if I went to Europe. Can the 4S connect to European 3G cell networks? If I get the 5 (unlocked from Apple's Canadian site), will it be able to connect to 3G and 4G networks in Europe? Thanks in advance for your help!
