Another classy one from AT&T:

Ars contacted Sling to see what exactly they did to optimize their code for it to get accepted by AT&T.  They said there had been no changes since the original submission over a year ago and that it had always been optimized for 3G network streaming.  

"We didn't change anything," Sling Media's John Santoro told Ars. "AT&T never discussed any specific requirements with us."

Santoro explained that SlingPlayer Mobile has always contained code to adapt the stream quality to the given network conditions. AT&T has been in discussions with Sling since it was first released last year, but AT&T never asked the company to make specific modifications. No changes were made to the app's 3G streaming capabilities between its being barred from AT&T and now.

That makes AT&T a big fat liar.  From their press release yesterday:

"Key for us is Sling Media was willing to work with us to revise the app to make it more bandwidth sensitive. They made important changes to more efficiently use 3G network bandwidth and conserve wireless spectrum so that we were able to support the app on our 3G mobile broadband network," said Ralph de la Vega, president and CEO, AT&T Mobility and Consumer Markets.

Grab the popcorn and prepare yourselves for some really awesome spin from AT&T. Oh, and if Sling is to make it past Apple's App Store gatekeepers, we're expecting them to have to pretend that they didn't make the above true statement.
