iPhone 4S cases showing up in retail channels?

Adding some validity to the possibility of a new iPhone branded “4S”, @chronicwire has just posted the images below showing the iPhone 4S branding on what looks like legit packaging for a new Otter Box iPhone case.

Another couple if you head down south. Notice the changed volume buttons that may or may not be indicative of a volume button to camera shutter feature.

LEAK: Photo of the back of the package showing the iPhone 4S case, depicting new volume buttons, and on the right side. New soft-looking volume buttons being on right side of iPhone 4S can probably be attributed to the “volume button to take pic” iOS5 feature

Update (Sept 23rd): TUAW talked to Otterbox who clarified:

She explained that the ad reflected the current conversations going on in the blogosphere. “Like many, we are watching the rumor sites and using information to plan ahead as much as we can.” Otterbox promises support for whatever iPhone debuts, but they’re emphatically not stating or leaking anything further. “We do not have any confidentiality agreements with Apple,” Richardson told TUAW.

As for those iPhone 4S Otterbox packaging photos that leaked yesterday, she explained, “What was circulating yesterday was not a case image for the iPhone 4S but a packaging design.” Otterbox has not identified the source of the photos.
