Something like that would be handy if I had a periodic need to block my number, but if I wanted it blocked all the time GSM is the way to go. Interesting comparison of feature sets.</p>

With CDMA (Verizon) you can have your number blocked permanently by having the carrier enable the "caller ID blocked" feature (which is no cost).

You may be able to do this on the Verizon's website. But it is certainly not as convenient as being able to turn it on and off on demand from the phone's settings.
