One of the more exciting applications for the iPhone is SlingPlayer Mobile, but unfortunately it appears less likely that it will be available when the App Store opens up next month.

SlingMedia produces the SlingBox, a set-top box that allows owners to access their television from either Mac/PC or Palm OS, Windows Mobile and Symbian mobile phones. Using a 3G connection, Sling Player Mobile allows for streaming of your television to a mobile phone. Sling Player software allows you to control your cable, satellite or TiVo box. You can watch live TV or access programs that you have TiVo'ed. SlingBox has no monthly fees and let's you access your content while on the go.

The bright, wide screen display on the iPhone would appear to be a perfect match for the SlingBox. The only issue was the lack of 3G and Apple's support for third party applications. Both of these objections will be answered next month with the release of the iPhone 3G and the App Store. Sling Media has developed a working version Sling Player Mobile for the iPhone, but it requires a hacked iPhone. The company has yet to be accepted into Apple's iPhone Developer Program, but they are far from alone. Apple has received over 25,000 applicants, but to date roughly 4,000 have been approved.

There has been speculation that software like Sling Player Mobile would cause heavy bandwidth usage and perhaps AT&T would like to curtail such applications. SlingMedia is not the only major developer anxiously waiting for their acceptance into the program. Rogue Amoeba, a company who has developed countless excellent Mac apps, has also blogged about their frustration with the communication surrounding the entire SDK approval process.

Both these companies develop great software and one can only hope their approval is in the works.
