SlingPlayer for iPhone will not work with older Slingboxes

So your sitting waiting patiently for the long promised iPhone version of SlingPlayer and you have been a long time user of Sling, looks like you may be out of luck. Original Slingbox, Slingbox AV or Slingbox TUNER owners will not be able to use the iPhone application. Below is the statement form the Sling site.

Sling Media is encouraging customers who own these earlier versions of Slingbox to upgrade to Slingbox SOLO or Slingbox PRO-HD to take advantage of next generation software and services that will only be supported when using the most current Slingbox and SlingLoaded products. Future software includes the highly anticipated SlingPlayer Mobile for iPhone software launching soon. Current Slingbox functionality will not be affected if you choose not to upgrade, but software like SlingPlayer Mobile for iPhone and future services yet to be announced will only be supported for customers using Slingbox SOLO, Slingbox PRO and Slingbox PRO-HD products or forthcoming SlingLoaded products

A little disappointing especially since I just bought a classic on Ebay in anticipation of the iPhone application hitting the App Store. Thanks to Sling Community for the heads up.
