I don’t know if this works on phones off the Sprint network?
If you visit this link from Blazer it will take you to Sprint TV live.
Sprint has also made available for download to select phones a Java application you can use to watch Sprint TV. I have not yet tried it. Rumor has it it works well but the picture is not as clear as other methods of watching SprintTV. It’s available for download in the usual places at Sprint.
Another .cab file has been released by the folks at PPC Geeks and is reportedly delivering Sprint TV to WM phones again.
