Everything I've heard indicates the different models are just a rumor. Especially the keyboard one. Keyboard really is not a huge option on phones now as far as a selling point, especially for Apple. They might do different models, but I really don't see it. And they usually are late adopters rather than early as it helps them keep as much "polish" as possible with their devices, as in, the least amount of possibility of errors and problems to tarnish their image. Not a dumb move at all.
