Your BlackBerry may soon be safer if you use a new kind of intelligent holster being developed by Research In Motion. The holster has a wireless chip that will send an authentication question to a recently removed BlackBerry--disabling the device if the correct answer is not entered. The question could be a password, fingerprint, or anything else. It's all explained in a RIM patent application filed in Canada although RIM officials did not comment. The wireless tether is not revolutionary, but it sounds useful even for keys and cell phones.
