Too bad it's GSM only. Verizon and Sprint are still on CDMA, I think.
I bought a cell phone jammer from this site, very cool gadget to have.
It blocks all USA networks, including 3G phones. finally some peace and quiet!

Too bad they're illegal in the U.S.
Naturally.
Can we sue the cell phone company if some retard is in a movie with the ringer turned on, or similar situation? 'cause, we paid to see the movie...
I could be amazingly wrong here, but I thought it would have been because of illegal broadcasting.
You're right, but you're using circular logic. Why is it illegal broadcasting? Because somebody else bought the rights to use that spectrum.
The case, however, that would still win in the Supreme Court would be based on health & safety concerns.
so is speeding, but i do that too..
unless you're being blatent about it, no one will ever know..

Hire someone discreet to build you one.
Nice and compact but as another user pointed out it's GSM only, which is fine in countries with only one cellular tech., but less useful in the US and Canada where CDMA is also quite prevalent.
Also, 10 metres isn't really enough to ensure peace in a movie theatre which for me would be the main application of such a device.
That was my thought too, except someone talking on a cell phone over 10 metres away in a theater is much less annoying than someone 5 seats away.
For users of GSM phones, such as those on AT&T, most people would blame poor AT&T service, not someone holding a jammer in the next row over.
I think a device like this would be great on the bus/train, where I always get stuck next to the person who enjoys holding conversations while their phone is set to speaker mode.
Most likely it just pukes out a bunch of RF noise from 850mhz up to 1900mhz which would also wipe out CDMA. Though CDMA is different (spread spectrum, code division) it still uses the same RF bands allocated to cellular in the US, so the jammer would most likely work.
CAUTION:
* Illegal usage may be affected the emergency caller
so you're going to hook this up to your cellphone signal booster doohickey and blot out phones in the area around DNA, right?
Wow, that would be dumb for so many reasons.
I want I want.
I'm not sure if mhagler was making this point or not. But I reiterate. Indiscriminate jamming of these signals isn't always a good idea. There may be EMTs, firemen or doctors in the theater who are on call and need to be in contact.
Most likely they are smart enough to use vibrate, but if you jam your half of the theater you could be blocking them as well.
Doctors use pagers. And there's a reason for that: you may not have noticed, but there are many places in the world where cellphones don't work anyway.
And in those many places in the world, pagers work? Why? Aren't they similar technology?
Wikipedia says: Most pagers in the US work on 900mhz bands, but there are also networks on 400mhz, VHF and FM.
Certain professions favor certain bands (probably more like: certain vendors that license certain bands cater to certain professions) but there's no breakdown of who uses what. Or for that matter what qualifies as 'most'.
Same bands? In other words, those jammers would also jam most pagers?
And I still don't see what makes pagers so special and different that they would work in many places where cellphones don't. After all, they, like cell phones, only work where they have reception of their particular network.
The only thing I can think of which might make pagers a bit more reliable is that I suspect that most pagers don't use bidirectional communications. They just need to receive, not to send.
On the other hand, the network knows when an SMS reached a cellphone, while with pagers, the network probably resends the message in specific intervalls (and the pager ignores every attempt after the first), but also only a few times?
The higher the frequency, the poorer the penetration.
Kinda like my sex life.

I'm waiting for the technology that not only jams phones, but also broadcasts a looped message saying "SHUT THE FUCK UP" over the airwaves.
What I want is some way to stop morons with Blackberrys walking down the street reading their emails, not looking where they're going and causing obstructions. (FFS, you'll be at your desk in 5 to 10 minutes!!)
Unfortunately the data is already on their device so I'm not sure what can be done :-(
I could see using this on the road to deal with drivers more interested in their conversation than in not killing people. Thing is, would the streets be any safer with said drivers staring at their phones, waving them around, redialing etc, trying to get a signal?
