I use Firefox with a lot of privacy-enhancing add-ons and would appreciate to see the same for Android. A start has been made with apps such as DroidWall, AdBlock, TaintDroid, Shark for Root, and BigTinCan AdFree Android. However, this is just a start. I encourage developers to take privacy concerns seriously and to develop apps that address them.
Please post here other privacy-enhancing Android apps that you came across or developed yourself.
