Can't wait to get my JB 7+... I ordered a Ringke clear case, but honestly I think I'm going to use it naked.
1) Let's be honest, if you're like me and a large percentage of people on this forum, you're going to get an iPhone 8 next year anyway.
2) I have AT&T Next 12,... I really, really doubt they will give people any trouble as far as exchanging it next year due to micro abrasions.
3) I'm getting AppleCare+... this means in 6 months or whenever, if I am really put off by the scratches for some reason, I can pay the fee and swap it for cosmetic reasons.
For all of those reasons, and because I personally liked the look of the 3G/3GS, I am excited to be getting the Jet Black!
