as far as I can tell, no one anywhere addresses what seems to be an obvious reason to have a call blocker...friends/acquaintances you don't want to talk. I mean, how hard is it to not answer a call? Noi very. I very rarely answer my phone for anybody except GF and family. What I want is something that will just give some innocuous unavailable message or simply give a busysignal or something so I don't have to deal with 4 voicemails during the course of the day from a friend that, it turns out, wants to talk about nothing. C'mon, where's the nerd power?!
