Interesting point, but what if this is also done at manufacturing on a larger scale? So Apple has their own variation of localized RSR technology for last min flow of finished goods before shipping? In other words the store variation is something that originated from the manufacturing process in use with iPhone production?
We’ve speculated about the existence of such devices for years. So far we’ve seen no confirmation of it. But I’m sure that if Apple doesn’t have such devices, they want to have them and are working on them.
