how to block unwanted calls and sms?

[bellpenn2]

Are you bothered with the annoying phones or text message? Sometimes they are annoying salesmen, terrible freaks，someone you do not want to contact with and so on. Now, I want to share you a useful windows mobile phone software to avoid this trouble.
The Pocket Call Blocker would help you solve the problem immediately. It is an effective and easy-to-use too to block all the unwanted incoming phone call. You could set your own rules to block any incoming call and sms from unwanted, annoying numbers, too. Let the incoming call and sms under your control.
If you have interest in it, you may search the internet by the keywords "wm sound recorder" to know more about it.

If you have a jailbroken iPhone you may want to try MCleaner. This will also block calls and SMS through the use of several custom or preset profiles.

There is also an app for this called Stop it !

Anyone can suggest the good app for doing this...

I switched to iBlacklist and I am very happy with it. It still requires the iPhone to be jail broken.

Give me a Call Blocker for Windows Phone.

There is is none available and I have been given to understand that WP does not have an API for it.
