Sling's updated their SlingPlayer iPhone app page, saying they're in "close contact" with Apple and are "optimistic" it'll be approved soon. Sling submitted it over a month ago, so it's pretty late. [Sling via 9to5Mac]
Screw Sling. Arbitrarily killing iPhone support for old players (Classic/AV/etc) to force them into an upgrade is not only shady, but an insult to the customers who helped spread the word and keep sling alive all these years.
Screw Sling, I'll take my money elsewhere.
