There is a great free Android app called Privacy Inspector which scans your apps to find out what they are doing with your phone’s information.
Most of this sort of info is collected and sold to advertisers.
In this example, I’ll scan the Engadget app to see what information it is snooping from my phone.
Looks like Engadget collects all sorts of info, including your Unique Device ID. Eek!
Post your findings to twitter, facebook, or via email!
Thankfully not all apps are evil. The Revision3 app collects … nothing! Sweet.
