I got lucky today, what a mess though navigating sprint.
The short story is that I found a manager who let me swap into a s7 edge with an exchange to a note 7 whenever they become available.
Here is the long story:
Called customer service, they were slammed and I was actually routed to tech support after 15 minutes. The person I spoke to just happened to be a n7 geek. She knew it all, down to FAA warnings and CPSC involvement. According to her, all websales, telesales and store orders have the opportunity to return or exchange their device for a full refund. Also, a revised policy has been set to allow note 7 customers who would like a note 7 long term to "exchange" (don't use the word "loaner" according to her) into a S7 (revised today from s7 edge or s7) and then swap back into a note 7 when new stock becomes available. I told her this sounded great, but I had serious doubts as to whether the retail store would even know where to start on this. She had no direct dial number, but told me she would call me in 30 minutes if I wanted to shoot down to the store and put her on the phone with the store reps. Her part of the story is finished at this point, but it did give me the confidence to go down to the store, reference corporate and roll the dice to see what I could do.
I get to the store. A girl with a "Manager" title very quickly agrees to my request to swap into a s7 until the new notes become available. We even start the process at the terminal but then she starts hitting system hurdles that are preventing her from proceeding. She asks the guy next to her for help who informs us both that if I want to switch into an s7 edge that is fine, but that is it. End of story. No exchange for note. At this point I am not willing to argue, and I thank them very nicely and go look at other phones waiting for the corporate call center rep to call me back. While I am waiting, the girl I was working with goes and speaks to who actually is the real manager. She reiterates my story about owning the note, and my embellishment that I travel twice a week and that the FAA wont allow these on planes. (I understand it is an FAA warning, and that I could take it on a plane but they dont

) The reality is that I travel 2-3 times per month, and dont have a trip planned as of right now.
A couple of minutes later, that true manager comes over to me and says that she understands my predicament and that as a "one off", one-time only deal they will allow me to use whatever phone is "appropriate for my needs" and trade it whenever the new notes come in. Boom done!
The exchange process took 45 minutes, and the manager was specific to the person I was working with to note my account with "heavy" notes. From there, another systems issue popped up and they actually had to return my note to have me buy the s7 edge. I needed to pay a $30 activation fee, and then have it credited back to my account.
At this point, I have a receipt with written notes on it as well as the "heavy" system notes to allow the exchange when the new notes come in.
I am really hoping that the new notes come in this week, that is what they are expecting. However, now that the gov't is involved, I can see this taking a while. I am happy to use and pay for a s7 edge while I wait even if it takes 2-12 weeks.
Anyway, that is my story. Happy to not have to worry about my phone burning the house down.
