I ordered an Otterbox Commuter case yesterday from Amazon that is for the iPhone 4 Verizon/AT&T phones, so it appears it'll be fine for the iPhone 4S. And it's $20 on Amazon instead of $35 for the iPhone 4S case from Otterbox on their website. The only difference between the two cases is a larger opening for the camera on the back, but the camera is identical in size and position between the two phones, so it won't be an issue.
