The leaks suggested that the Verizon iPhone would have slightly relocated buttons, and it's true -- as you can see in the photo above, the newly revised CDMA antenna notch has pushed the volume and mute controls down a hair from GSM version. That means a lot of cases -- Apple's current bumpers included -- won't fit properly on the Verizon version, although many third-party cases feature an open slot for the buttons that might still work. Either way, we'd bet Apple and third-party manufacturers are scrambling to have compatible cases in stores before the February 10th launch date -- just make sure to check yours first if you're switching from AT&T.
