Earlier on Tuesday, we went over T-Mobile's new pricing plan for its smartphones, and we discussed how all new phones will remain locked to the carrier until they are paid off, mostly to protect the company. But Sievert explained that T-Mobile will sell you an unlocked Apple iPhone right out of the box if the MSRP is paid at the time of purchase. And if you start paying for the Apple iPhone 5 via the installment plan and pay off the balance, any T-Mobile store will be able to unlock the device while you wait. By the way, to keep T-Mobile an arm's length from the pricing process, the price for the phone is determined by Apple. This way there can be no accusations that T-Mobile placed a premium on the price of the phone.
