Hello Everyone,

The following is based on documentation from Microsoft: 

Anytime you receive a call from a number that is not in your phone’s Contacts list, you can add that number to a new or already existing Contact from the Call History list. 
 
Here Is How To Do It on Windows Mobile 6 Smart Phones: 

1.
From the Start Menu, select Call History.

2.
Highlight the number you wish to save.

3.
Tap the Right Soft Key to bring up the Call History Menu.

4.
Select Save To Contacts.

5.
To save the desired number as a new Contact, do not move the highlight bar and tap the Left Soft Key or select an existing Contact and press the Left Soft Key.

6.
Scroll to the desired field where you want to store the number and select Insert.  If you are creating a new Contact, the “Save to Contact” screen will open, where you can enter the first and last name as well as any other information you wish to save.

7.
Finally, select “Done” to save the new information. 

That’s all there is to it.
