I have just came out from a T-mobile store and asked a rep about the unlocked iPhone 6 plus. He told me that if I buy it DIRECTLY from apple it will came unlocked, he even verify this with another of his co-workers.
What I did was to wait until the shipment estimate was about 2-3 or 3-4 weeks, as of now. With that time frame, the iPhone 6 will come out and I am sure that one of the headlines of the launch day will be if the iPhone is locked or unlocked to T-Mobile. If it is locked, I just cancel my order and patiently wait until the unlocked one appears; if it is unlocked, I just let my order as it is.
Because I am from Mexico (sorry for my English) The 14 days return policy do not apply for me because I don't know if I will be able to be in the USA during that time frame, and if it is locked and I am not able to return it, I will be in serious troubles.
And if everything that I have said didn't convince you, my actual (hope not for too long) iPhone 5s was bought directly from apple last year with a T-Mobile SIM card, and it came factory unlocked.
Hope it helps. Regards.
