Why does Apple do this? If you shell out full-price for a supposedly unlocked phone, you should get a phone that works with any carrier in the U.S. and any network worldwide. It's not until the "sim-free" phone becomes available that you get this. So in effect those shelling out full price for the iPhone 7 at launch are getting LESS of a phone than those who wait for the sim-free version a month or so down the road. It's only the sim-free phone that will work with AT&T, Verizon, T-mobile, Sprint, and other networks in the U.S.; networks in China; networks elsewhere in the world. It's these sim-free, work-everywhere phones that will have the highest resale value, and with good reason: More people will be interested in them. Bigger audience. Plus, I like to travel the world. I don't want my full-priced iPhone 7 crippling me from the get-go. Booo, Apple. Dumb!
