Unpacking webOS .ipk files on a Mac
Posted by Shane O'Sullivan on August 28, 2011
Quick tip: For some reason, the archive files that webOS uses as application installers are very awkward to extract on a Mac. It’s simple on Windows.
After a little digging, I found a handy script at http://forums.precentral.net/webos-development/235149-extract-build-ipkg-mac-osx.html that does the trick.

Glad I stumbled on this post. I’ve been wondering how to do this on Lion.
Laura – webOS isn’t dead yet! And is Lindsay Lohan into technology?? (not sure I follow).
