On Wikipedia there is an
HTC Model Chart which muddy's the water further by suggesting that Wizard and Podigy are interchangeable.
I'd suggest that, given that everyone here knows what someone means when they say they have a Wizard device and that only Cingular have ever released the other type, we just accept that Wizard and Prodigy are one and the same and move on
It's a bit like someone saying they have a hoover, when they actually have an Electrolux Vacuum Cleaner. Everyone knows what they mean so it doesn't matter that it isn't strictly correct.
