The SlingPlayer Mobile ($29.99, iTunes link) app is now available in the iTunes App Store—SlingPlayer having just received permission a few days ago for video streaming over AT&T’s 3G network. If you’re unfamiliar with SlingPlayers, they are devices that let you stream video from your home’s TV and/or DVR over the Internet to any device that supports SlingPlayer software. You could be on vacation in another country and sign on to watch your local news through the iPhone. You can also use the app to control your DVR, setting it to record shows, browse through TV listings, etc.

Of course, to take advantage of the app you’ll also need a SlingPlayer device, which range in price from $150-$250 on Amazon.

SlingPlayers can control your TV and other devices. It supports a wide range of devices, including:

  • Cable set-top boxes and DVRs
  • Satellite set-top boxes and DVRs
  • Tivo
  • Telco / IPTV set-top boxes and DVRs
  • Basic cable
  • Digital Over-the-Air broadcasts (Slingbox PRO-HD only)
  • Apple TV
  • Home security cameras

While this makes for a sweet iPhone app, it’s going to be an even better iPad app thanks to its larger (and more comfortable) screen.

SlingPlayer Mobile is a $29.99 download from the iTunes App Store.
