When I installed the facebook app, all my friends then appeared in my contacts list. Some of them don't have a phone number stored on facebook, but I do have their number on my sim. Rightnow I have some people with 2 contacts. 1 is the facebook contact, and the other is the contact from my sim with their phone number on it. Is there any way to 'merge' the 2 together so I have 1 contact for each person with phone number/facebook/email etc?
