This problem has been bothering me for a while. When I add a phone number with the name of my friend that is the same on my facebook, sometimes it just couldn't find the right one to link to?! Also, the worst part is even I link it manually, I can't find the contact on the facebook for HTC?! However, I can find contact perfectly with the facebook app on the phone or on the computer. I just don't know why somehow my facebook contacts are missing while I try to link them. Anyone has the solution for this? P.S. I sync all the stuff I can sync already and it doesn't help. The solution I found before is that wait for a couple of days and suddenly it would just show up and YES it's LAME.
