We admit, the vibrating alerts in some phones are extraordinarily loud, often too loud to be discreet. And if the phone is sitting on a hard surface? Forget it. Motorola's BUZR could be years away, if we ever see it at all, so what's a mischievous, cellphone-toting student to do when phones are banned from class? Rumors are flying that students in the UK have recorded the sound produced by a device called the Mosquito, designed to disperse roving gangs of teenagers by emitting a sound that can only be heard by youngsters. By using the recording as their ringtone, they hear it (along with their friends and any nearby canines) while the poor headmaster is left in the dark. It's debatable whether your average cellphone is capable of producing sounds in the range necessary to elicit this effect, so this may be nothing more than a rumor, but if you see packs of dogs belting out some tunes near the local high school, you know what's probably going on.

If you need to turn that ringer off in a movie theater or meeting, but find that the ol' vibrate mode just isn't doing it for you anymore (or if you need a surefire way to wake yourself up in the AM), Moto has the answer: shock mode. The company has filed for a patent on what it calls "a system that allows a cell phone to set off electrodes on a stimulator pad, alerting users of incoming calls." Moto also notes that the system can be used for "therapeutic stimulation," and that customized patterns -- think of them as the shock equivalent of ringtones -- can be downloaded to enhance the experience. We assume it'll only be a matter of time before someone figures out how to use this as a weapon (or at least a 21st century alternative to the joy buzzer) as well. And if you thought you had trouble getting through security with your camera phone, just give it a try with one of these babies.
