Yes, that is correct - at least that's what was said on the news channels
here in the UK. The Spanish bombs were triggered by mobile phones set on
alarm at 7:39am IIRC - the phones didn't even have to have SIM cards in
them. No signal jamming equipment could have prevented them from going off.

Ah - the modern equivalent of the classic alarm-clock timing
mechanism. Modern digital watches would work about as well.

As to the idea of jamming cellphone frequencies: even if physically
practical, and even if the government would authorize widespread
distribution of devices which jammed a licensed radio service
(doubtful IMO since the cellphone companies paid $$$ for their
licenses and would doubtless fight it in court), it would only move
the problem elsewhere. There are far too many radio frequency bands,
and far too much commonly-available equipment which could be modified
to allow for remote detonation control over moderate distances. Garage
door openers with rolling-code security, portable radios of all sorts,
etc. could all be incorporated into a scheme for remote- controlled
mass murder by those whose inventiveness and skills outweighs their
ethics and humanity.
