Bought a 3G from a friend. It does not currently have active servive on it. I checked online, and the warranty is active. But the round "Home" button does not work. I have another Iphone that is active, but on that one I am using a Blackberry SIM for data only. If I bring the unactive one to Apple, will they swap it even though it is not active? Or, should I put my Blackberry SIM in. Will they care? I will go there tommorow morning. What is the best approach?
