Originally, Apple didn't include "Shared Photostreams" on the 3GS but added it back during the iOS 6 Betas. However, I cannot make a shared Photostream on my 3GS. I was under the impression that all I do is this: go to Photos, press Edit, then tap on the pictures I want to share, then tap Share, and finally go to "Share Photostream" or something. Any one have any idea what's going on? Thanks in advance.
