Goodbye, iPhone 6-branded silicone and leather cases.

Apple has already begun updating their Apple Store displays in preparation for this Friday's iPhone 6s and 6s Plus launch, and one casualty: A surprising lack of "iPhone 6"-branded cases.

Spoiler: Those iPhone 6 Apple-branded cases may be no more. They certainly weren't on display at the store I visited in Providence, RI. Instead, everywhere I looked in our relatively small store, iPhone 6 and 6 Plus signage had been replaced with titles advertising their newer models. They're gone on Apple's online store, as well, replaced with a neat little virtual try-on room for various color combinations of phone and case style.

This recent change has left a few shoppers rather confused. While I was shopping, I heard "Where's all the iPhone 6 Apple cases? I need iPhone 6," from a girl next to me, complaining to her shopping companion.

What they didn't know is that iPhone 6s and 6s Plus cases will fit their last-generation cousins. The devices are virtually exteriorly identical to last year's models, and as such, leather cases and silicon cases alike fit without issue. (You can see a few of my try-ons of 6s cases on an iPhone 6 below.)

Unfortunately, that may not help confused shoppers who aren't quite as savvy about phone dimensions. Tip: Flip the box over for a very tiny 8-point font notation: "Compatible with iPhone 6 and iPhone 6s."

Aside from sizing, the new iPhone 6s and 6s Plus cases come in a variety of pastel colors to mirror the new Apple Watch Sport Bands, as well as the traditional brown, light pink, and midnight blue (now of the Apple Watch Modern Buckles).

Of course, for those wondering: Yes, this means you can use your iPhone 6 case with your 6s, too. And probably non-Apple branded cases, as well, though I haven't had a chance to test any of those quite yet.
