Step 1: Buy an iPhone for $200 from AT&T
Step 2: Sell it unopened on Ebay/Swappa/etc for $600 ($50 less than Apple sells it for)
Step 3: Buy an unlocked HTC One for $575 (no tax and free shipping!), and you just got yourself an unlocked, unbranded One for $175, almost $50 cheaper than you would end up paying for AT&T?s crapware laden version after tax.
