Apparently terrorists used cellphones to detonate their bombs in those attacks last month in Riyadh that killed thirty five people, including nine Americans. Lest this news induce a new round of panic about cellphones and their risks (that they cause brain cancer or that they interfere with airplane navigation systems, etc), terrorists have been using pagers and radios to set off explosives for decades, and if they couldn't use cellphones, they'd just turn to one of those. Or they could just go back to using timers.
