Thank you. I'm glad you understand what I'm talking about.
I care about resale value, and I don't want to deal with the hassle of explaining to a potential buyer (especially someone overseas) whether or not a phone sold with a carrier's name on the receipt is the same as an official "SIM-free" version. I also do not want the IMEI number connected in any way with a carrier. I don't care if the carrier versions are unlocked and I don't care if they have the exact same functionality as the official "SIM-free" version because I am ONLY interested in buying the official "SIM-free" version.
If anyone has any educated guesses on when the official "SIM-free" iPhone 5S will be released in the U.S., please post.
In years past at least, the sim-free iPhones tend to show up when demand and supply equalize. The shipping times for the iPhone 5S recently improved to 3-5 days so I'm going to *guess* that in the next month or so we'll see a sim-free version or perhaps sooner.
