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.

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

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.
