Windows Phone has a great integration with Facebook, that surely helps. But a lot of my contacts are divided across my personal gmail, official emails, LinkedIn and Facebook.

But surely my address book if far away for being complete. Either few are missing phone numbers, emails, or pics.

I try to manually unify all my contacts into Gmail, since that's what I mostly use for email, and I can sync them to my phone. But it's definitely missing entries. It's weird that this is such an unsolved problem.
