[corresation]

The discussion had nothing to do with being SIM unlocked or not, but rather constraints that remain whether you paid full price up front or not.

However the "on a contract" bit is frequently misrepresented I think: when you get a device on contract, in most cases you are being loaned the cost of the device. You have zero recourse to simply return the device when you decide you don't want it any more. There is little to no difference between buying a phone "outright" on a credit card, or getting it "on contract" with your carrier.
