My experience today-
Thought I would stop by the store this afternoon in case they had them in a day early. Did a Samsung Smart Switch backup of everything onto the SD card on my way into town.
They did - they had just come in less than an hour before. Store was busy, so i watched a poor rep swapping all the data on a couple's 2 notes - bet that took a good long time! It took a while to get with a rep, but once I did it was less than 20 minutes to do the trade. She just activated the phone and made a test call, then we put the SD card in and I was on my way. I didn't have any of my accessories with me and that didn't matter. She said they'd keep the box and put the old phone in it. She then asked if I wanted the headphones from the box - I said no, I have too many cheapy sets already. 'What about the charger or cable or adapters?' she said. Well, yeah, I'd like all of that stuff if that's alright. I asked 'hey, what about the s-pen?' and she said 'keep it'. So I left with a new note and a second full set of accessories!
Went out to my truck and started smart switch going, then ran to the grocery store, and by the time I got back to the ranch it was all done. And I had 2 sets of accessories and a second s-pen. Very happy with the whole process (I know, the rare satisfied VZW customer).
Oh, and she said they had a whole pile of them in the back, so if you're anywhere near Baghdad... (not that Baghdad is near anything)
*Changed location as I don't want the rep to catch any flack for hooking me up with all the accessories
