Patch is finally available. Comments are saying it unlocks automatically.
Just heard back Feb 3 2015
"I've seen your messages & I can assure you we are still working on it. It's a high priority for us but it's a difficult bug to track down and fix where it will also retroactively apply."
Fingers still crossed
Apparently as of yet no progress has been made.https://twitter.com/izret101/status/549989395227750400

As of now (i believe the game is ver 1.02) this achievement appears to be unobtainable.
I completed the collection from Italy on the phone and got nothing for it.
I only have 3-4 collections left to complete so i am hesitant to test more in case this and
don't end up getting patched to sync. I would caution others to make sure they also leave 3 or more incomplete collections in case it ends up being required.
One person has both achievements unlocked so i would assume they got it on an earlier prerelease build.
