Sometimes I make trips across the state and was wondering if it was safe if you take a Sim Card out of an iPhone and put it in another phone (say for ex: my old Razr) and when I'm done, put it back in the iPhone? Also is the iPhone still operable without a Sim Card in it? I still want to be able to use it to play music in my Jeep through Aux mode and an Aux cable.
