Just get any full priced version except for Sprint if you can find it in a store. They will be unlocked, regardless of what the rep says. They don't sell the SIM-free model here until a few weeks after launch. But all Verizon models are unlocked, and if you pay full price at Apple, so are the AT&T and T-Mobile versions. Last year on launch Saturday I went to my local Apple Store and asked what they had for sale "device only, contract free." That's the code for "unlocked" provided it isn't a Sprint model (they refuse to unlock their phones at all except for customers, and only for non-US SIMs). Don't ask for an "unlocked" model because the reps will just say they don't have them yet.
