Is there any way for me to use the features in the 2.6 firmware without upgrading from my 1.5 firmware? I would like to take advantage of the WMA playback feature and the Web browser on occasion, but I don't need either feature all the time. And obviously I'm not going to upgrade my firmware. I know there are browsers and media players out there for the 1.5, but the built in ones seem nicer. The homebrew media players that I have played with so far, didn't work all that well.
