I want to upgrade my s4 to a used Bell locked S7. Is there any way to get it unlocked for free (after Dec 1)? Can I get a friend on Virgin to have them unlock it for free? Not sure of the easiest and cheapest way to get it on my Koodo plan. If I have to unlock it on my own, can I go the ebay route ($8), or is the phone hardware locked. I don't have a nano-sim to test.
