Motoblur - Account Linking

[terrrrrible]

I have a Google, Facebook, Twitter and last.fm account all set up on MyMotoBlur. It seems that only Google and Facebook are the only ones that are linking with my contacts. Some people in my list I know have all four accounts, and their last.fm and Twitter accounts aren't showing up. When I go to My Contacts and select Twitter, it doesn't say I have any contacts. If I go to last.fm, they're all there, but aren't linked their actual contact. Is there something that needs to be done?

Also, is there an option to choose from which profile you set the display picture as for the contact? My girlfriend was telling me how to do it from her G2, but it may just be a feature of that phone, and not on the Atrix.

Something I noticed, I manually tied together a contact with their last.fm account, and now they show up as their last.fm username in my phone book. How do you change the display name?
