My buddy Edwin let me know about a free application in the BBRocks! Store called Antair Boxee Remote by Antair Corporation. As the name implies, after downloading this app you’ll be able to control your Boxee TV right from your BlackBerry smartphone.
Not being a Boxee user myself, Edwin says he likes the app very much but the only drawback is having to manually set it up before using it. The app is available as a free download and will work on most BlackBerry devices running OS 4.2 or higher. If you try it out let me know what you think in the comments!
