Two articles discuss spamming to cell phones from the New York Times:
"Cellphone customers received roughly 4.5 billion spam texts last year, twice as many as in 2009, and remedies to the growing menace are few."
"The Haggler revisits the subject of cramming -- the act of tacking on an unrequested service fee to a phone bill. Why, he asks, can't cellphone carriers do more to thwart it?"
Also: "In airports, laptop computers get special attention from the T.S.A. Similar devices don't. The reasons are a mystery."
