FYI, if you opted into the FB picture sync, be aware that it will sync every photo you take like every 20 minutes or something. If you're like me, and take multiple photos of your toddler to try to get a non-blurry one and then don't automatically delete the extras before the sync they'll all go into the private FB album. Which wouldn't be a huge problem but suddenly realizing 7 or 8 months later that you haven't cleared out the sync folder means you're stuck with 2k+ photos and no easy way to delete them (FB says to delete them one by one!)

I found out a way to make it go quicker, but geez it's a PITA! Either turn it off, be better than me about deleting the bad photos right away, or delete the synced photos more often!
