Call Blocker or Call Firewall for WP7
 

Guys,

I have a Sprint HTC Arrive WP7. Lately I'm getting a lot of telemarketing calls from some Home Protection. It`s always the same two numbers, they call a few times every single day. Very annoying... My number is on Natioal Do Not Call list, a lot good it does....
Are there any apps to block calls for WP7?
