I have been working on adding content to the webOS Gospel Library application. If you would like to try my unofficial version, which includes October 2011 General Conference and the 2012 George Albert Smith manual (plus tons and tons of other content - basically everything that you can download for the IOS and Android versions), then you can grab the IPK here: http://bricxcc.sourceforge.net/org.lds.webos.gospellibrary_1.0.4_all.ipk
In addition to the application you will need to grab the content, which is not yet downloadable from within the application. I separated it out into its own zip archive because it is a large amount of data and storing it separately from the application is a step toward supporting in-app content downloading (which I am working on). You can get the content here: http://bricxcc.sourceforge.net/webos_content.zip
The zip should be extracted to the root of the drive that is created when you connect your device to your computer in USB Drive mode. On a PC it might show up in Explorer as D: or E:. Use 7zip, WinZip or Windows built-in support for compressed folders to extract the zip to your device. It should create a folder called ".ldssa" which contains a "content" folder which has all the original XML content plus all the additional content that I have added. If you have any questions about this you can email me at afanofosc at comcast dot net and I will try to help.
