The best buy option is a good one for anyone that is looking for GUARANTEED launch day availability. Between AT&T and Best Buy, I now have 2 orders from each (I like to have fallback options). The best buy store manager told me that if you select a specific store online, it will tell you if they will have a specific model on release date. You just have to go to the model you want and click pre-order and then select a store near you. He said they are pulling all in-store inventory and giving it to those that pre-ordered. I was able to get a 64gb iPhone 6S Plus in Rose Gold and another iPhone 6S Plus 64gb in Regular gold. Both are sitting safely at the best buy store already.
