Portable Cell Phone Jammer

Here’s one gadget that can be really annoying if placed in the wrong hands. This portable cell phone jammer is capable of jamming cell phone signals such as GSM850, EGSM900, DCS1800, PCS1900, CDMA800, WCDMA/CDMA2000, PHS, DECT and even 3G, within a radius of about 32 feet in all directions. Though the battery will only be good for 1.5 hours of mischievousness, that’s more than enough to spoil your colleague’s day. Fortunately this device won’t come cheap, as it’s currently going for $246.
