Ok, so my search results include :
1) fraudulent advertising from amazon and ebay trying to sell
phone bags as 'jammers'. . Though I also got a result from
amazon in india apparently selling an authentic jammer. (side
note: so the amazon cancer already spread to india).
2) a couple of sites allegedly selling jammers but whether the
sites are run by the government or not seems hard to tell...
3) make article

linking to this broken link...
http://blog.makezine.com/archive/2006/12/wave_bubble_ope.html
but this seems to be the original source
http://www.ladyada.net/make/wavebubble/
(project seems a bit too complex)
I also found this
http://cdn.preterhuman.net/texts/government_information/intelligence_and_espionage/homebrew.military.and.espionage.electronics/servv89pn0aj.sn.sourcedns.com/_gbpprorg/mil/gps/index.html
(originally from phrack it seems)
...and some other stuff. All of it it seems rather old, though
the information is obviously still valid.
So there's more stuff than I originally thought though of
course all the new articles are about the horribly catasthropic
dangers of jamming.
