Everyone is saying that the backs on the iPhone 4s are not interchangeable with those on Verizon or ATT iPhone 4. I have personally tried a custom back that fits CDMA and its fits the iphone 4s pretty well, in fact, perfect. Has anyone who is saying it wont fit actually tried it? I have tried it with multiple CDMA iphone backs and they all seem to fit fine.

The CDMA panel mostly fits on to the 4S. The CDMA panel does not align perfectly, as you can see in the photo. But it is enough that it will screw in place, and won’t interfere with the camera. Note that the model numbers on the rear panel are not the same as the 4S.

iPhone 4S supports both GSM (using Micro SIM! the “old” big SIM will not fit) and CDMA. Source: iPhone Jailbreak and Unlock

i did. works and fits perfectly. ir’a just the labels that are different

i just tryed to install my old GSM iPhone 4 back on my new GSM iPhone 4S, and its not gonna fit. the brackets on the back is not aligned the same.

The iPhone 4S is a world phone, so there are no cdma only or gsm only models. There is only one gsm+cdma model.

We had a sprint 4s come into the shop today, and the cdma back did NOT fit. It is close but not good enough to give to a customer.
