yes from appple store, unlocked.
Strange... usually iPhones from Apple Store are truly unlocked, versus SIM-free (which means it will lock to the carrier of the first SIM card inserted). Stores like Best Buy, etc. used to sell the "SIM-free" versions which make it easier for them to stock a single "generic" SKU, which locks to a carrier afterward. Are you the original purchaser? You can have an Apple Store "Genius" confirm the "activation policy" on the phone, and then you can have the last carrier unlock it...

you have to contact previous cell provider and ask for a free unlock code. Apply code to free up the phone.
It's noteworthy to mention that there's no unlock code provided for iOS devices; unlock status is maintained on Apple's servers, and not on the device itself. To unlock, the carrier simply adds the IMEI to a list that periodically gets sent to Apple's servers, authorizing an unlock. Upon doing so, the iPhone will be authorized to use a different carrier SIM when it authenticates against the activation server.
