TechEBlog spotted an ultra-rare Star Trek Communicator cell phone by Nokia that is "intended to simulate the iconic voice comms devices of the original TV series."
A working cellphone made in the form of a Star Trek communicator. This is one of 14 numbered prototypes distributed internally at Nokia in 2008. I bought it on eBay from a former Nokia employee who received it as a gift and no longer works for the company.
This is a heavily-modified N76 with custom sounds, graphics, and hardware. It is very much a prototype and obviously in a late Alpha or early Beta stage.
