Motoblur Cliq xt help?

so this new phone is supposed to sync my contacts from social networks. and even tho i have this awesome phone, my parents gave this to me without 3G internet (or texting, but that's besides the point). anyway, is there any way i can sync my contacts without the 3G internet by the service provider (mine's T-mobile btw) using Wi-Fi? i remember doing it once because all of my contacts and profile pictures got updated even without the 3G connection. but i don't recall how i managed to do it.
