Next Generation iPhone leaked

Just a short note: Outsourcing always means giving away information which prior only belonged to one company. It therefore carries increased risk of theft, be it physical or intellectual.

In the last days several videos showed up on youtube showing what might be the next generation Apple iPhone.
Usually these videos are published from bloggers or the press, sometimes money for the device/video is paid.

But I would be worried much more about the pictures, that are not published… Presumably competitors like Sony-Ericsson, HTC, etc. might be willing to pay much more to get a hands-on glimpse on this device.

How can companies prevent this kind of risks? Is insourcing the only option?
