So does anyone know if the Verizon iPhone 4S will be locked to the Verizon Sim? I talked with Global Support yesterday and they said they the phone will be able to use other sim cards. Just like in the past, you just had to call them and get a unlock code. A few minutes later she called be back and told me the information she had given me before was incorrect. And that you wouldn't be able to change the sim card because you cannot take off the back cover and remove the battery. I'm not sure she knew that she was talking about. I would assume all the iPhones would be all the same physically and have a micro sim slot on the side.
