Hi everybody, i'm looking for a sim-free iPhone 5s, but on the Apple Store i can only choose the T-mobile contract-free model (and of course the contract models). I want to buy it to use it in Spain. I see that the 4s and the 5c have the contract models, the T-mobile contract free model, and the sim-free GSM model, but not the 5s. When can we expect a sim-free GSM iPhone 5s model? Thank you very much.
