title: Determine Android version
body: <p>I have bought a 7'' pad from a chineese supplier, claiming that it is a 'Android 2.0'. But in the settings menu I read this:</p>
  
  <p>Firmware version: 1.6
  Kernel version: 2.6.29-00236-g48dbbb-dirty
  Build number: WMT2.1.2_105</p>
  
  <p>The supplier points at the build number, claiming that this is the 'Android version'. What is the significance of 'build number', anything to do with the 'Android version', or unrelated?
  And, what is really my 'Android version'? </p>
