Are locked phones really unsubsidized? Not $200 subsidy, obviously, but maybe $50 or $100, considering that Virgin expects you to use it with a $30+ monthly plan and would treat it as a customer acquisition cost.
True it isn't unlocked, but I'm not aware of anyone saying unsubsidized == unlocked.
You can buy a Virgin mobile phone and never activate it. You can stop paying without penalty after your first month. That's unsubsidised.
