2.1 Update :: Linking Contacts With Their Facebook And Twitter On 2.1

I just recently got my xperia x10 and had to almost immediately upgrade to the 2.1 system. I am noticing a few things that I'm not fussy about from the 1.6 system but the thing that is bugging me the most is that I cannot (figure out how to) link contacts in my phonebook to their facebook and twitter accounts. In 1.6, when you edited a contact it gave you the option to click LINK. I cannot find any of this on the new system. As well, for contacts that I had linked before, their facebook profile pic (current from the time when i linked them before upgrading to 2.1) shows up on their contact information (i usually only link facebook, as i dont use twitter as much) and their profile is linked. However when i go into EDIT, it says FACEBOOK, Timescape and a big exclamation mark that has a message beside it saying : Timescape Plug-In Manager contact information is not editable on this device. i SHOULD be able to edit and link all my contacts. that was the whole purpose of the xperia having this timescape program.
