I had this problem since I updated to the 2.1v3 leak when I open any of my contacts with photos, contacts would force close. I didn't change any settings on my phone, but what I did was go into my Google contacts and delete all the FB links from the notes portion of the contacts. As soon as I did that, presto, everything reappeared correctly and my contacts are again linked to their FB accounts. Don't know why this got messed up in the first place, but for those of you sick of having your contacts force close, I thought this might help. Apologies if this has already been posted elsewhere. I was just so excited that I fixed it!
