Chosen Solution

If I purchase a 16 GB or larger iPhone 4s mother board will it work in my iPhone 4S with 8GB of memory? You show out of stock for any iPhone 4S boards that work with my carrier (AT&T) will you be getting more or are they gone forever?

Herve Gelinas yes you can switch the boards. As for if iFixit gets the AT&T boards back, we the volunteers on this board cannot answer that. We are not directly connected with the business side of iFixit. contact the iFixit staff directly on here
