title: Wrongly indicate not enough memory when installing the app
body: <p>I am developing an app with Eclipse SDK Version: 3.6.2 and Android platform 2.2 r3.
  I have set android:installLocation="preferExternal". The app also correctly installs on the SD-card on my ZTE with Android 2.2.</p>
  
  <p>But...</p>
  
  <p>The installation fail when the <strong>phone</strong> memory is less than the needs for the app I am installing.
  It seams that the installation program check the phone memory instead of the SD card.
  Is there any fix for this?
  Can this problem appear also when the app installs from Android Market?</p>
  
  <p>Hope someone is kind enough to help me on this. I am planing to release the app shortly. </p>
