The New Android Mobile OS Forensics

Hi everyone! As you might know there is a new open source mobile operating system called Android!

Im doing some research into this and was wondering if any of you would have any idea's as to what programs would be cool to create that would help us in a forensics investigation! Bare in mind the application will actually run on the phone itself

An example is an app that can triangulate a contacts address using google maps and show you the distance they are from you!

The code is written in java, but the platform in LINUX based

help would be apprieciated =]
