no unfortunately it will not,
its the only annoying setup process you have to go through when you get your phone.. I exported (saved to desktop) all my contacts from the backup assistant's page online (didnt even know it was there before), then imported them into my google account... from there I was able to sync the contacts to the phone, then finely link each one individually to the appropriate facebook account... it took a minute, but when its done ... its done , i hope this helps
