SlingPlayer for the iPhone has been one of the most anticipated apps for the iPhone. It has been delayed many times for various reasons, but that may change tonight. MacRumors is reporting that Apple is going to be releasing the application tonight for customers to buy, however it will run you $29.99. Downside? It will only run on Wi-Fi, no 3G or EDGE. This has been confirmed with many Sling Media sources, so look out for the application tonight.
