Apple execs might have said that the iPhone 4S looks and feels the same as the iPhone 4 and it appears that the form might be the same but the fit definitely is not the same.
According to one Android-Sale Blog, the switcher and volume key buttons of iPhone 4S have been moved down slightly, which are going to render iPhone 4 cases useless for the iPhone 4S. This might have be done to accommodate the new dual-antenna design in the iPhone 4S to solve the ‘antennagate’ issue.
Notice the extra slit on top of the switcher button. This might be bad news for existing iPhone 4 users who are buying the iPhone 4S but the case manufacturing industry would certainly be rejoicing. They will have something new to sell, especially after Apple hoodwinked them into making ‘iPhone 5′ cases with a new slimmer design and larger display.

Already we have seen about a 100 different interpretations of what Apple’s iPhone 5 might look like at this point, and we all probably agree that October 4th can’t come soon enough; regardless of what Apple is going to introduce next month, it will finally put an end to the rumors and speculation.

According to technology blog AllThingsD, the well popularized Apple plans to unveil its next generation iPhone next month. AllThingsD has cautioned that Apple could “change its plans anytime,” but said that the present plan calls for Apple’s new chief executive Tim Cook to preside over the launch of the iPhone 5 on October 4.
According to a media report, the website of an accessories manufacturer has updated to show what were apparently cases for Apple‘s forthcoming iPhone 5. Though the page has been quickly removed, it triggered intense speculation about the shape of the next iPhone. It was put up on a product page published on the Case-Mate website.
