'iPhone 4S' cases already arriving at AT&T stores

This might be the strongest evidence yet for the iPhone 4S. I don't think this gives conclusive evidence of there not being an iPhone 5 model in the works, if I remember correctly, the only iPhone 4 "case" available at launch was Apple's own bumper.

I love my iPhone 4 (despite its cracked rear glass) and the thought of the same design with a faster processor and better camera are nice additions, certainly.

I just won't be upgrading based upon those changes, alone. A true iPhone 5 release might be a different story, however.
