Crazy link man.

Anyway, anybody with the right radio hardware 
and a little Linux box with OpenBTS and maybe
asterisks (or other software setup depending)
can roll something like this out...

Last i checked it didnâ??t support 3G but the phones can
be tricked into switching down to 2G unencrypted 
if you blast a strong enough signal. Newer phones maybe 
more resilient?

I donâ??t know how much more advanced the commercial 
stingrays are over the best roll-your-own...

There are android apps that do IMSI catcher detection, 
but they have some issues.
