I'm in Canada and had my JB iPhone 4 replaced at an Apple Retail store. I restored phone as new in iTunes prior to going to the store. I even added some apps so the phone wouldn't appear so new. I was informed that it was store policy that the iPhone be scanned prior to giving me a replacement. Didn't do that when I had my iPhone 3GS replaced 4 months ago😕 Perhaps Apple is scanning to determine if the phone is Jail Broken? The Apple employee plugged in the dock cable into my old phone and was checking the info on a store iPhone. The replacement iPhone 4 is a refurb.
