Hello, I was wondering if I was to replace an iPhone 4S 64GB at this point. What IOS version would it have? Is there any chance that it comes on IOS 7 instead of something lower or higher. I doubt that it will come with IOS 8 at this point but neither do I want it to come with anything IOS 6 or below. Preferably I would want it to have IOS 7.1.X.
