I use Go Contacts because it lets me save my contacts on the phone, instead of with Google. Personal preference.
After the upgrade, I had to re-import my backed up contacts. I also noticed that my contacts kept disappearing from the "Phone" account in Go Contacts and moving over to the "Google" account.
I thought I'd found a bug in Go Contacts, but after a little more poking, I think I found the problem. Under System Settings -> Backup & reset, "Back up my data" was on by default. I turned that off, and my contacts seem to have stopped getting moved.
Long(er) term, I don't know what the "correct" solution for this is. Perhaps someone can port the backup program Paul627g's been touting to OS X and I can use that for a "full" backup. For now, I'll just keep using my "partial" rsync-based occasional backup to my laptop at home. Perhaps this is a moot point because I'm an outlier as someone who doesn't want their contacts in Google/gmail.
