I take some of that back -- I remember using PGPfone over a dialup in '95 and its performance at the time was impressive. Compare that to the first GSM network going live in '91. But PKI's use in GSM is only for network authentication and not en/decipherment of all traffic. Either way, networks and mobile stations are constantly being upgraded which is why Bluetooth tethering is a boon for anyone that's not as keen on upgrading every year or two. -Gary
