The general idea is to not let "them" see you have a hacked unit. Hence the no phone calls. Possible reason - they might get "pissed" and do something nasty to "undo" what you did (and the rest of us too). No there, for the most intense purposes, will not be any software updates, but you wouldn't want your unit to get one anyways since that too would undo all the nice things you can now do. Now some people are using Caller-id on thier units and the phone lines are plugged in but the calls are still blocked.

I guess the question is what convenience are you referring to by leaving the phone line plugged in ?
