can I unlock the iphone 5c if i bought it from apple store?

If you choose the "unlocked and contract free" one then it is unlocked. The others are not locked and require a 2-year contract with a phone provider.

I purchased my iPhone 5 directly from Apple. There was no need to get it unlocked, the one I chose was already unlocked (factory unlocked, meaning it was never locked in the first place).
