I got a chance to stop by an Apple store today. There, I asked about them PM'ing their straight up [ un-subsidized price for iPhone ] sale with T-Mobile's.
The rep [ or whoever he was ] said they are PM'ing with T-Mobile with the following conditions:
1) Apply for a Barclay's card [ Apple's way of financing ]
2) Based on your credit worthiness, make a down payment [ matching T-Mobile ]
3) You get 0% financing to pay off the phone at a minimum monthly charge and up on making the final payment, they will refund/credit the Barclay's card with the price difference aka Price Match.
So, for example they will *finance* a 16GB iP5 for $649 + Tax and then refund/credit back $70 to match T-Mobile's price of $579 AFTER you have paid $649+Tax in full via minimum monthly payments or one/several large payments prior to the end of the 0% term, which is set forth by Barclays.
Basically, from what I understood, you'll have a $70 credit on your Barclays card, unless Apple writes off the last $70 so you don't end up with a credit, but a $0/null/no due balance.
I hope that makes sense because no one, at the Apple store, knew exactly how this would pan out blaming it on it being the first day selling a T-Mobile iPhone with their *new* plan.
What he, and others, also did not know was whether the financing @ 0% will be for 6/12/18/24 months. That is something Barclays would decide!
The upside, from what I was told, is that the device will be unlocked at the time of purchase.
So...that's the low down....if correct!
