I have a rooted Optimus-V and just installed Droidwall. Whitelisted all the apps I thought needed to have internet access. When I open an app that I guess needs access, but isn't checked, my phone starts playing music at max. volume, and the volume buttons won't turn it down (until it's on mute). None of my music apps are open. Is this a "feature" of Droidwall to let you know it's blocking something? Very irritating! edit: uninstalled Droidwall, installed Adfree... no more random music. Very odd, because I don't think the songs playing were on phone!
