Lost cameras "phone home" to catch thieves.

"GadgetTrak, of Beaverton, Oregon, sells software that can be loaded onto any of those devices. If a BlackBerry, for example, falls into the wrong hands, the software grabs information from the new user's SIM data card and e-mails it to the rightful owner. With an Apple Mac computer, the software instructs the built-in camera to take video of the thief and sends to the owner, along [with] information about nearby wireless networks."
