When
you delete a contact card, the information is removed from both your
phone and the account the contact is associated with (except for
Facebook contact cards, which can’t be edited or deleted directly.) If
the contact you’re trying to delete has multiple linked cards, you have
to specify which account profile to delete.
1. Delete a Contact
In the People hub, flick to All, and then tap the contact you want to delete.
Tap Delete. In the confirmation dialog box, tap Delete.
Tip:
To delete a Facebook contact, you need to do it from your PC web browser.
2. Delete a Linked Contact
In the People hub, flick to All, and then tap the contact you want to delete.
Tap Delete.
Choose the account associated with the contact. When you see the confirmation dialog box, tap Delete.
Tip:
You can also delete a contact by pressing and holding on the person’s name in the People hub, then tapping Delete.
