With Call Blocker by NQ mobile you can block any number you want. Do you have a stalkerish annoying X? Maybe a telemarketer offering you magazines or vacations? What about that collection agent that is calling the person who had your phone number five years ago?
All of those people can be added to your block list. Or, you can elect to only let calls through to your device that are in your contacts list. Also if you use Google Voice and have it set to let the actual number through caller ID instead of your Google Voice number, you can use Call Blocker with it.
