The mod linked to in the first post appears to be outdated.
I was able to download the current APK from one of the links above (not otherwise available in my region), and got through the tutorial. When I went to install the mod from the first post, I got a message indicating I need to download the most current version from the Play Store.
I wasn't able to simply install the mod over the existing APK. I had to uninstall after using Titanium Backup, install the mod and then restore data. Not sure if that why it is not working, or if it is just the mod link being outdated.
