Help Syncing Contacts and Numbers

[katamari]

I have a ton of Facebook contacts that I synced into my contacts list. However, not all of them list their phone number on their facebook. When I try to add a number, it says "Facebook contact information is not editable on this device". How can I add a number to a contact synced through Facebook?

Easy way for me is to make a GMail contact in the web interface and add it there, then the app will sync the facebook information with the existing contact.
