Reserve device as IUP, pay full price instead?

Hey everyone,
Now that some devices are showing up as available on IUP for for the 16th, I was wondering if I could reserve 2 phones for IUP, but then go into the store and buy the phones outright instead?

I have T-Mo, so I wouldn't be able to renew my IUP online, I'd have to go into the store anyways.

I have 2 phones on order with a delivery date of Oct 5-11th, no issue sticking with that. But I don't want to reserve phones and cancel my order only to be told that I can't buy them both full price on the morning of the 16th.

 

I currently do have 2 phones through the IUP. My original plan was to pay off these two, and then start a cycle of buying my phone outright.

 

Looks like this answered my question, and now I'll be getting my phones on launch day!!
