I just ordered two iPhone 6S+s. I paid full price and ordered using the app on my iPhone. It defaulted to replace the phone I was placing the order from. If I chose to order a phone without a contract the T-Mobile logo would come up. So, since I chose to order from Apple and replace the phone I was on (I am currently on AT&T) will I get AT&T phones or will they be unlocked since I paid full price? Also, how will I be able to tell when I get them if they are unlocked?
