Not sure what aspects of Flash you're referring-to, but SB does not support Flash Audio, although I understand some stations transmit a Flash user-interface and standard audio stream.
Regardless, I grabbed my SB Duet Remote, searched out CFNY. The Duet quickly found, and is now happily playing 102.1 the EDGE Toronto aka CFNY.
BTW, the SB Radio is cute, but I assume that you know it's only half an SB Boom, right? You're giving up the 2nd (integrated) speaker for a 2.4" LCD screen, the only benefit of which is to display radio station/podcast logo's or album covers.
