iPhone users looking to stream TV shows from their SlingBox know too well that until now, the iPhone SlingPlayer app would not work on 3G. SlingMedia has apparently developed a new app that is optimized for 3G, and AT&T has agreed to allow the streaming on their network.

"Just as we’ve worked with Sling Media in this instance, we look forward to collaborating with other developers so that mobile customers can access a wider, more bandwidth-sensitive, and powerful range of applications in the future," said Ralph de la Vega, president and CEO, AT&T Mobility and Consumer Markets.
"Collaboration with developers like Sling Media ensures that all apps are optimized for our 3G network to conserve wireless spectrum and reduce the risk that an app will cause such extreme levels of congestion that they disrupt the experience of other wireless customers. Our focus continues to be on delivering the nation’s most advanced mobile broadband experience and giving our customers the widest possible array of mobile applications."

"We’re delighted with AT&T’s decision to approve the SlingPlayer Mobile app on their 3G network," said John Gilmore, senior vice president and general manager at Sling Media. "SlingPlayer Mobile on AT&T’s 3G network gives customers the best experience possible for watching their home TV while on the go."

There's no word on when the app will appear in the App Store, but surely it won't be too long.
