On my old phone (mytouch slide) it was very easy to link a phone contact with a facebook profile but I can't find a way to do this on my new G2. Can anyone help?

When I took the sim card out of my old phone and put it in the G2 many of the contact info transferred, including link to fb profile, but not all. What I'm trying to do is: go to phone contact for Joe Smith and link it to Joe Smith's fb profile so that it'll pull in contact picture, etc. thanks for the help.
