I am a BB user right now but may be interested in trying a Iphone. Does anybody if my current simm card can be used in the new Iphone 4S? I think I saw somewhere it will require a mini simm card of sort. The reason I ask is I want to just be able to switch my simm card between the 2 devices. I may have to go with just the orginal 4 model. I am not willing to pay a arm and a leg for something I may not like but I would go $100 on a Iphone 4 in perfect shape.
