Ok, here is the Official Sprint reason for SprintTV not working on the Mogul. This is quoted from an Email I received from Sprint:
"As far as Sprint TV on the Mogul, we have not blocked the feature. The Mogul (and a few other Sprint phones) has the Microsoft Windows 6 program built into the phone. This program is not compatible with the Sprint TV feature. It simply does not work. Unfortunately there is not an estimated time if this feature will be able to work with the Mogul.
The best advice I can give is to keep up with the latest downloads and upgrades available for the Mogul. A great way to do this is to visit http://softwarestore.sprint.com/."
Sounds like the company BS being dished out to us to keep the bandwidth usage down, but that is just my opinion.
