In preparation for the Verizon iPhone, Apple has quietly altered their existing iPhone 4 Bumper Case design to fit both GSM and CDMA versions alike.
As you might recall, the Verizon iPhone is visually identical to the AT&T version except for a slight change in the antenna design, which Cupertino insists is not so much related to Antennagate as it is to the requirements of Verizon’s CDMA network.
That antenna change required Apple to move the mute switch slightly closer to the volume buttons on the Verizon iPhone, which means that the old iPhone 4 bumpers wouldn’t fit a Verizon iPhone.
Apple’s solution? Make the space around the mute button a little less snug, hopefully by altering the mould as opposed to employing a warehouse full of Asian children armed with dremels to widen the gap.
