Q: I would like to download my old contacts from my Samsung into my new iPhone 5C. How do I do it????????????

I have tried using the bluetooth on the iPhone to search and pair with my ol samsung phone but it is rejecting the pairing? I would hate having to download the contact info manually. Is there a way to do this?

Additionally how can I get teh iPhoen to work with a hands free bluetooth decise that ie especially helpful when driving. The earphones supplied with the phone are in my view quite a dated alternative.
