DroidWall - Root Permission Required for Android Publisher's description
A firewall for Android.
A firewall for Android. This is for users that don't have an unlimited data plan. It allows unrestricted WiFi access, however it blocks all access over the cellular network unless you add the application to the whitelist.
NOTE: I did not develop this. All props go to Rodrigo Rosauro, who released it on XDA-Dev. Good work!
System Requirements:No special requirements.
Program Release Status: New Release
Program Install Support: Install and Uninstall
