Looks great. I'll have to give it a try after work today.
One feature I've always wanted in a call blocker is a timer. What I mean is, I'd like to set my phone so that all calls in the blacklist are always blocked, but from, say, 1AM-8AM, all calls are blocked except those in my whitelist. If my mom needs to call me for emergency reasons, I don't want her not to get through just because my phone didn't ring. I've yet to see this in any call blocker for Android, even though it was a fairly common feature in Windows Mobile. And yes, I'd be willing to pay for the call blocker that offers that feature!
