Can not say if it is installed on TouchPad during install, but all IPK have a control.tar.gz and a data.tar.gz.

Apps do not seem to have a md5sum, but they all seem to have a control file if one looks in the control file and compares one would notice the difference between App Catalog Builds...
As Version 3200: webOS-Packager-Version: 3.0.4b35
As Version 3220: webOS-Packager-Version: 3.0.5b38
As I consider 5b38 different then 4b35 I am assuming this is the build version of the packager that is building the App Catalog.
So as the packager version has changed and that is part of the SDK, I am assuming they are testing the new SDK (webOS 3.0.6/2.2.5)?
