If you’re hankering for a Verizon iPhone and worried about needing a bumper case, Apple may be a step ahead of you.

Per Engadget, Apple has apparently worked around the problem of needing two versions of its Bumper case with the pending launch of the iPhone 4 on Verizon’s network by creating a universal Bumper. The new Bumper case includes a larger switch slot that accommodates the slightly different positions of the mute switch on the two iPhone 4 models.

The iPhone 4 bumper Apple shipped months ago for GSM-based networks like AT&T, O2 and Orange, the handset using a different antenna configuration than the new CDMA-based model that will sell for Verizon’s network. That change meant Apple needed to reposition the mute switch that sits just above the iPhone’s volume buttons, making the company’s current Bumper cases incompatible with the new model.

It’s unknown whether the bumper will be free (as was the case with the iPhone 4) or available via retail.

Stay tuned for additional details as they become available.
