Marlinspike's Droid Firewall Kills Tracking 164
mask.of.sanity writes "The first dynamic Android firewall, dubbed WhisperMonitor, has been released by respected security researcher Moxie Marlinspike. The firewall will allow users to stop location-tracking apps and restrict connection attempts by applications. Marlinspike, whose company created the application, designed WhisperMonitor in response to the incidence of location tracking and malware on Android platforms. It monitors all outbound connection attempts by applications and the operating system, and asks users to permit or block any URLs and port numbers that are accessed."

Not dynamic, but allows you to setup white/black lists of application to access 3g or wifi network.
Does a good job. You just have to remember to add new apps to the white list of you want to allow them access to a network.
