*67 has been widely used to block your Caller ID from being seen. But did you know that you can turn off your Caller ID with Windows Phone 7? That you can also limit who can see your Caller ID?

Simply go into the Settings Menu, swipe over to Applications and choose the Phone. The Caller ID settings are down below your Voice Mail number, maybe half way down this page.

You will see the setting, "Show my caller ID to:" with the options to:

  • Let everyone see your number
  • Let nobody see your number
  • Only allow your caller ID to be seen by your contacts.

It's a nice feature of Windows Phone 7 to help keep things private when need be.
