Sling Media has released the latest version of its SlingPlayer Mobile iPhone app, complete with 3G streaming capabilities ($30, App Store). The app, which allows users to watch and control their home TV and DVR, has been available for several months now, but was restricted to WiFi use. The restriction was reportedly enforced because of network congestion concerns on AT&T's side, however, with the announcement of major updates to the companies 3G network this may be less of a concern.
