Sling Media, makers of the Slingbox place-shifting TV device, is building a version of its SlingPlayer software for the iPhone and iPod touch.
SlingPlayer, currently available for Macs, PCs, and numerous cellular phone platforms including Palm, Windows Mobile, and Symbian, connects those devices with Sling's Slingbox hardware so that the devices can display live or prerecorded TV across the Internet.
You won’t find any info on the web site, but SlingMedia showed prototypes to press at Macworld in USA. But you can see a cool video on how SlingPlayer works on Blackberry and other cell phones.
