If you have an AT&T iPhone 4, you might find that your current iPhone 4 cases won’t fit the new iPhone 4S. According to a photograph provided by Android-Sale, the buttons and volume switches have been moved slightly, now reflecting a design similar to the Verizon iPhone 4.
While this may come as a concern to some AT&T iPhone 4 owners, it was not unexpected, as the iPhone 4S antenna would have to be somewhat different than the AT&T iPhone 4 in order for the device to handle both GSM and CDMA wireless carriers.
Some AT&T iPhone 4 cases may still fit, and any case designed for both the AT&T and Verizon iPhone 4 should definitely fit the new device.
