Apple official website's serial number query is iphone5s. Why is the space release to show the iphone5?

It may be a revision machine, that is, a machine modified by applying the 5S shell to the a 5 motherboard. As for the serial number, the serial numbers of both the revision machine and high copy machine are real serial numbers, which are collected by profiteers from various forums and post bars, and then brushed on fake machines. Otherwise, giving a fake serial number will not be exposed at once!
