T-Mobile iPhone return/replace question
On launch day I bought the iPhone 7 128gb due to the fact that T-Mobile could not fulfill my 7 plus preorder, I used carrier financing. I have adapted to the smaller screen but I just found that my local Apple store has the 7 plus 32GB in stock. I was able to reserve one for pick up at 100pm today.
So my question is this, what is the better way of doing the return. Go to the apple store and do the carrier financing through them for the device and return the 7 to the T-Mobile store, or should I return the 7 to the store then go to apple? I am thinking option 1 since if there is an issue, I will still have my 7, but then again option 2 clears up that line for the new phone.
