In advance of the Verizon iPhone, it seems Apple realizes the old bumper won't fit. So they quietly stocked Apple Stores with a new, universal bumper where the hole for the mute switch has been enlarged just enough to accommodate both versions of the iPhone 4. Nice! We were wondering when this would happen, and it's a bit in advance of the Verizon iPhone actually being available. Let us know if you spot them in your neck of the woods.
Thanks for the video and tip, Alex!
