PlayOn TV for iPhone finally approved
PlayOn Mobile is a free app that works with a subscription service ($39.99 for first year, $19.99 after that or $79.99 for a lifetime subscription) to stream content from a number of providers to your device over Wi-Fi or 3G. Before you get too excited, though, note that you need to be running PlayOn PC on a Windows PC to get that streaming goodness on your iDevice -- there's no media server software solution for the Mac.
The PlayOn content providers include Hulu, MLB.tv, Netflix, Comedy Central, CBS, MTV, TV.com, PBS, SpikeTV, and The Ultimate Fighter, as well as others. Plug-ins can be developed for PlayOn's media server to grab other content -- my personal favorite, The Food Network, is listed on there.
