A:AnswerTo get most of the regular channels you still have to have some sort of TV provider but Roku just makes it wireless so it can be watched anywhere. I haven’t looked at all of the packages that they offer, and there’s quite a few, but there may be some that you can subscribe to that you can get regular TV through and get rid of your satellite but you still need to have a wireless network for this to work. So you need a network provider at a minimum.
A:AnswerI think they all run the same OS and it is side loaded, not jail broken. Roku's official channel store provides a large number of channels to add and watch. But most of the services are premium and few of them are free. ... You need to sideload the app to Roku. Currently, the sideload option is only available plugins and ZIP file but not for APK files.
