HOW DO I BLOCK A PHONE NUMBER ?
You have to download a third party application from the marketplace.
I can't find any on MarkerPlace.
Hi granslm, I am not aware of a third party app for Windows Phone in the marketplace...there are others who agree this is something that is needed http://answers.microsoft.com/en-us/winphone/forum/wp7-wptips/windows-phone-7-call-block-list/8a58b61a-af7d-4be8-a988-483bcf99d7df but unfotunately it does not seem to be an option at this time.
You can always add Family Allowances. I use it all the time. It's a $4.99 a month but definitely worth every dime. You can add it on T-Mobile.com under the change services/features.
