Leaked engineering samples of an unreleased iPhone are the new thing. In past years we saw lots of leaked iPhone cases before an iPhone release.
Yesterday KitGuru released photos of an iPhone 5 engineering sample. The photos got a lot of attention. The iPhone 5 model shown was though actually very unpolished. Not something Apple would be dealing with. My guess is that this engineering sample was from a iPhone case maker. This is what they work with in anticipation of the real deal.
In any case. Today KitGuru posted a not that they took down the photos. Quote "Due to external pressures, which we are unable to detail publicly we felt it necessary to remove this story and all related images."
I do not think that the "external pressure" came from Apple. Do you?
