A:AnswerMy research has shown me that the safest purchase for an unlocked phone and a guaranteed trade in on your existing iPhone is to purchase it directly from either Apple online or from an
Apple store.
A:AnswerWe eventually got for free ($800 trade in) but don't trust accuracy of Best Buy or Verizon online to calculate trade in value, which depends on your plan and carrier. Take to a Verizon or your carrier's dealer to confirm trade in value.
A:AnswerNo. BestBuy only sells Iphones tied to a carrier plan on Verizon, ATT, TMobile. You would need an unlocked version of the iphone, which is available directly from Apple.
