The Verizon iPhone has one amazing distinguishing feature over the AT&T iPhone and that is the 5 person Mobile HotSpot. Any WiFi capable device will be able to connect to the iPhone and share the data connection. AT&T has not said any word on whether or not they will be allowing this feature, but in iOS 4.3 beta this feature just works. Users have been reporting it works directly with their current tethering plan, and the fee's for the AT&T mobile hotspot on other phones are exactly like the AT&T iPhone tethering plan. Hopefully this will be accessible on the AT&T network when iOS 4.3 is released.
