Will I be able to purchase the iPhone 6s in-store on the release date?(T-Mobile)?

Added (1). I'm planning on buying the new 6s when it comes out on the 25th after I get out of school. We don't have any Apple stores near where we live and the best place I can go is our T-mobile store in the mall. Tri-cities, WA. Will I be able to purchase the phone there or will I have to preorder it and have it shipped on the 25th?

Yeah you will but there will be limited quantities, and if you're expecting a rose gold, show up early because there will be limited quantities. I would show up to your local store a good 2-3 hours before hand just so you have dibs. You can also pre-order now if you don't wanna wait in line. They will ship it to you.

You've to be in the queue then.
