West Ham vs Wigan Streaming
Live Radio Commentary is available on BBC London DAB Digital Radio & Satellite channel 0152. Because of the cancellation of the QPR game the West Ham game is now being broadcast on analogue radio as well.
TV Streaming is apparently available via ViperTV. This is a peer-to-peer service that I've never used and I don't know where to download it. This thread on WestHamOnline discusses the feed.
