Just wondered if you are able to watch tv from your iphone? Haven't read too much about this plus I have no idea because I've only had mine for about 2 months.
Right now the only way to watch live TV on the iPhone is via Orb. You need a PC (no MAC support yet) with a compatible TV tuner and the Orb app. installed on both the PC and the iPhone.
Slingbox has been working on an app. for months, even shown a beta off but no release date.
