Updated: The text version of all of the conference talks is now available through LDSScripturesApp.com. (For the text version, all of the talks are in a single file). We spent quite a bit of time on formatting the talks so they look professional and very closely match the published talks from LDS.org. As you can see below, every talk also has a picture of the speaker and all references to the scriptures will bring up the corresponding scripture in the app when tapped on. Here's a screen shot directly from the LDS Scriptures app:

The entire audio recordings for the 179th Semiannual General Conference, October 2009 are now available through LDSScripturesApp.com. The recordings are separated into six different files, one for each session (including the Relief Society general meeting). To find them, just search for the phrase "179" (without the quotes) on LDSScripturesApp.com or from within the "My Library" section of the LDS Scriptures app.
They are large files (around 40MB for each session) and will take a while to download to your device.
