Re: encrypted cellphones

Cellphones, of course, can only (usefully) use encryption if the cellular service provider uses it (i.e. if the end that's listening to your radio transmission can decode it :-) American cell-phone providers don't. The GSM phones used in much of the world have encryption, but it's apparently not very strong.

Don't forget the more attractive option: End-to-end. Why leave the plaintext available for the cellular provider? Eric
