I can't remember the official 4.03 OTA update notes, but it does include something about "social networking blah blah", but from what I've read, Google and Facebook can't get together on some code. There are ROMs that have bypassed it and have gotten it to work, and zygot3 2.0 hasn't done so yet. He is working on 2.1 and it will have it in it. So just hold tight for the next update and it will be included.
