Can I buy the iPhone 6 from the Apple Store and still set up a payment plan with T-Mobile or no?

I have the iPhone 5S from T-Mobile. Contract Free. Do I have to go to a T-Mobile Retail store to set up a payment plan? Or can I go to the Apple Store and have them do it for me?

I think that if you want to purchase the phone and make payments on it, rather than paying full price up front, you need to do so directly with T-Mobile, whether via their website, calling 611 or going to one of their retail stores.

Yes the APPLE store will do that for you, but depending on the provider you pick, the Apple store can sells you JUST an iPhone at full retail, letting you pick the cell provider and plan of choice at a later date (what many people do for gifts).

Or they will sell you a phone with the carrier and plan options setup and ready to go for you to activate, either there at the Apple store or at the cell phone providers store or by the phone of the provider, your choice.
