1. Battery life. If it's at all Nano-sized, then battery life will be non-existent. Phones use much more power than music players, so the battery will have to last longer, too.
2. Multi-touch. If the screen's not multi-touch, then the whole iPhone OS goes out of the window. Even at iPhone screen size, using the keyboard is a squeeze - any smaller and you're back to alphanumeric keys, Option menus, no differentiation from any other phone.
3. Patent applications: Are no indication of shipping products, just protecting general areas of possible interest (and maybe even providing a bit of smokescreen for actual products).
4. 2nd Gen iPhones: this is not to say that Apple shouldn't be looking at expanding the iPhone range. For a start, they should obviously be looking to introduce a 3G/HSDPA iPhone - slightly bigger, but can put more storage, bigger battery, maybe even GPS in. And charge a bit more for. Existing iPhone can then become the cheaper, less featured version, and Apple's margins will allow it to reduce considerably in price if necessary.
5. Price: Apple has been very clever at keeping wide areas of differentiation between their products, so that the high margins are never obvious. Produce an iPhone Nano that is effectively just a Nano with a SIM card, and where do you price it? The alternative is to bury the margins in the overall AT+T plan, but then...
6. AT+T: People will switch networks, even to AT+T, for a breakthrough product. Will they do the same (and lock themselves in for 2 years) for a cheaper, simpler, more ordinary one? I don't see it myself.

Reasons why an iPhone Nano will not happen:
1. Battery life. If it's at all Nano-sized, then battery life will be non-existent. Phones use much more power than music players, so the battery will have to last longer, too.
2. Multi-touch. If the screen's not multi-touch, then the whole iPhone OS goes out of the window. Even at iPhone screen size, using the keyboard is a squeeze - any smaller and you're back to alphanumeric keys, Option menus, no differentiation from any other phone.
