My sister is interested in the 1020, and she has a 4S. She wants it unlocked because she is going to France for 6 months, and doesn't want to pay the international plan. I know they have the 6 month waiting before unlocking, which is fine, but does that policy still work for people who bought the phone on contract. And if she buys it from the Microsoft Store, does that policy still work? Hope you say yes, so she will buy it in white. Thanks!
