ok guys, this thread is pretty old (thought it was dead for a while) and the first post is outdated. the most recent stock ROMs have SprintTV included and you can get the OEM from the PPCKitchen, but not sure about a cab file...gotta be one floatin around here somewhere... anyway,
http://ppckitchen.org did a major update to their site a while back, and well that's prolly why the link in the first post doesn't work...
