iPhone 4 Cases May Not Fit iPhone 4S

New iPhone 4S

If you’re planning to use your GSM iPhone 4’s case for the new iPhone 4S then we may some bad news for you. It may not fit if you had bought your case especially the iPhone 4 bumper before the Verizon iPhone was launched in early February.

The photo below gives a side-by-side comparison of the CDMA iPhone 4, GSM iPhone 4 and the new iPhone 4S (left to right), respectively. You’ll notice in the photo how iPhone 4S and CDMA iPhone 4 have the volume buttons and the mute switch in a slightly lower position than the GSM version. This is because of the black band that separates the antennas, a design change that debuted in February with Verizon’s iPhone 4. The buttons were moved down to accommodate this change and this carried over to the new iPhone 4S.

This change prompted Apple to redesign its original bumper back in January. You can see the image below, which gives a side-by-side comparison between the original iPhone 4 Bumper and the universal iPhone 4 Bumper that has been available since the launch of Verizon iPhone.

Many third-party iPhone 4 cases are designed with space around the mute switch and volume buttons or have large cut-outs in that area. You may not have to buy a new case if your iPhone case falls in that category. On the other hand, if you have an original Apple bumper, you may need to buy a new case for your iPhone 4S.

Before buying a new iPhone case, it may be prudent to try the case on your iPhone 4S to see if it fits.
