It's been getting worse as the months pass. I get approx 1 telemarketer call a day now. I google each number and there's lots of people complaining about the same phone numbers-all telemarketers. Is there a setting (or tweak for jailbroken iPhone) that will mute or completely block these unknown calls not in my contact list? DND is not an option, as DND mutes text messages and I can't have that. Any ideas guys?
