It should work like this according to earlier posts.
1. Download the Sprint tv cab, the cache file and the rar cab
(if you don't have rar allready)
2. Install rar cab on your device
3. Install Sprint tv cab on your device
4. Use the rar program to unzip the Cache file you downloaded
to {Program Files > Sprint TV} on your device.
5. Run Sprint TV and enjoy.
Won't work for me
