The T-1000 is a cellphone jammer that looks like an old-school cellphone. Much like how the T-1000 from Terminator 2 obliterated the Governator, the T-1000 cellphone jammer will obliterate cellphone signals. The T-1000 can block phone communication within a 3- to 10-foot area of effect. It'll keep blocking up to 60 minutes per charge and it's effective against a host of cellphone technologies: AMPS, CDMA, TDMA, PCS, GSM, DCS, Nextel, iDEN and 3G voice.
Now you can enjoy watching movies in silence with this little dandy in your pocket. If you want to be really obnoxious, pretend to talk on the phone while you're using it, watching everyone around you shaking their phones and yelling, "Hello? HELLLLO?!". It's available for $240, but buy at your own risk because there's a good chance using it would be totally illegal.
