Last night after operating an application called aLast.FM Player my phone volume went mute even though the mute setting was turned off. At any rate I had to restore my phone to its original settings. When I did this one of the features did not work anymore. On the headphones that come with the G1 there is a button that can be used to start and stop songs from the music application and when pushed twice shuffles to the next song. After the reset this feature no longer worked. I have looked through the settings but I don't see how I can turn this feature back on. How do I get the feature back?
