A YouTube video posted yesterday reveals that Apple has released new bumper models that are compatible with both the existing iPhone 4 and the CDMA iPhone 4 set for release on Verizon next month. With the primary difference in physical features between the two models being the location of the mute switch, Apple has widened the cutout in the bumper to accommodate either switch position.
Apple has also updated its online store with new "B" model numbers for the bumpers, replacing the original "A" models. The company has, however, yet to update its product images to reflect the modified mute switch opening.
Meanwhile, BGR reports that Apple has issued a blackout on vacations for its U.S. retail store employees between February 5th and 18th in order to handle the expected rush generated by the Verizon iPhone when it launches on February 10th. The company is also reportedly planning for extended hours at its store to handle the crush.
