Ya know I'm totally not sure! I do know that buying any model outright makes it come unlocked. Last year I purchased a sprint 7 Plus and popped my ATT sim right in.The T-Mobile version is only unlocked to gsm not cdma networks right?
*fingers crossed* I hope soThe sim free version was on the website prior to it going down. So it should be available for preorder.
Sim free model is available for pre-order this year."Sim free" no
T-Mobile versions which come unlocked and you can pay full price for... Yes!
The difference between the two isn't really anything. But Apple usually doesn't sell "sim free" models until a couple of weeks in.
