Here's hoping I can like the jet black when it finally gets here... because I also have a thing for black black black high shine gunmetal style electronics (the black Note 7 looked so sleek). So I'm hoping the fact that it's black will let me live with the change.
Chances are when the anniversary happens it will be another white one for me though. Lol
I'm not sure if this is the case yet with all Best Buy stores, but I was at one of the ones in town today and they had the iPhone 7 display up @ the front of the store (including both a Jet Black 7, and a Matte Black 7 Plus), so it might be worth a trip there to see them in person for yourself if that's an option for you.
As for my time there, I ended up doing some case shopping as they had cases out from Modal, Platinum, tech21, Case Mate, Insignia, Otterbox, and others.
