Stolen Phone Database
This article talks about a database of stolen cell phone IDs that will be used to deny service. While I think this is a good idea, I don’t know how much it would deter cell phone theft. As long as there are countries that don’t implement blocking based on the IDs in the databases — and surely there will always be — there will be a market for stolen cell phones.
Plus, think of the possibilities for a denial-of-service attack. Can I report your cell phone as stolen and have it turned off? Surely no political party will think of doing that to the phones of all the leaders of a rival party the weekend before a major election.
