Let the hive mind of Engadget get that for you.
"I own an iPhone 3G and I'm looking for a decent speaker / alarm clock for it. I am going to listen music in a mid-sized room, so I want nice quality speakers with solid bass. I also want to use it as an alarm clock, so it would be great if there is such a feature. The price can be low-mid to mid-high range. I was looking at the Klipsch iGroove SXT; it's powerful, slick and the reviews are good, but it doesn't have an alarm clock feature. It's no deal breaker if I can set it up from the iPhone, but I'm not sure. Thanks!"

Now last I checked edge has no problem supporting that. The problem however is that Apple like always would like to control everything and I doubt Sling will go for that. Plus Blackberry gave Sling more than a generous offer considering the stiff competition that BlackBerry has been facing for the last couple of years...
