What would you plan to connect to/through the Express, and how? If the Express is going to be using its wifi to connect to the iPhone, only the ethernet port(s) would be available to connect other computers.

Do you mean to somehow plug your iPhone, or other 3G modem, into the USB port? If so, it doesn't work.
The only other way would be to use the WiFi "Personal Hotspot" feature and "join" the Express to the WiFi network, but this wouldn't extend.
