Welcome. This is addictive so kiss your normal phone usage goodbye by adding a lot mor testing and experimenting! AND HAVE FUN!
SK works on CM9. Just uninstall it completely and reinstall. I use Titanium Backup when I uninstall. You can then get rid of data that might prevent proper operation of apps. All roms are not created equal. So with some apps you will find that a complte reinstall is required.
OK, I see. I used My Backup to transfer my apps. I'll try reinstall when I find things that don't work. Thanks!
