, the makers of the Slingbox set top box and SlingPlayer software have taken the beta label off the company's BlackBerry client. What that means is if you own a Slingbox and have it plugged into your home theater setup, you can stream live TV to your BlackBerry - for a fee. The SlingPlayer Mobile client will set you back $30. There's a 30 day free trial if you don't want to commit without trying the software out first, but you'll also need to have a Slingbox. There's no way around that constraint (unless you've got a friend who's willing to let you login to his or her Slingbox account).
Sling also has mobile clients for Windows Mobile, Palm, and Symbian. And it looks like an iPhone client is on its way. There's a new SlingPlayer for iPhone web page
which shows a software demo video, and you can sign up for an email notification
when the program is added to the iPhone App Store.
