Add mobile number to Facebook contact? My Android phone connected to Facebook and grabbed all my friends. Now I want to edit their info and add a mobile number, but it does not let me do that; it only lets you change their ringtone and a few other little options.

I am also using GO Contacts from Go Launcher. It's a little annoying when I click "edit a Facebook contact" and it goes to the phone's default contact sheet. 

If I click a person I input manually it will go to that person in the Go Contact app and give me extra options and all that good stuff.

Is this a problem with Go Contacts or something? Can anyone recommend something better? Needs to have a dark skin.
From your contact list, select the Facebook contact that you would like to edit.  Click the menu button and choose Edit Contact.  You'll see an indication that the user is a Facebook contact and may not be edited.  Now click the Menu button again and choose New contact.  This will create a new contact in your address book and merge the Facebook profile information with that contact.  You may now edit the contact to have additional details, such as a phone number.
