It's hard to tell what features will be unlocked, your best bet is to call Samsung and ask them directly.
Unlocking your phone for a fee won't necessarily void your contract and it will let you switch between different carriers with the same phone using different sim cards. At least that is how it works here in Italy.
Feature-wise, though, I don't know. I think it depends on the particular phone you're using.
