DO NOT INSTALL SBSETTINGS. It works but it screws up your springboard and it will cause you the touch responses to fail when trying to get into cydia to remove sbsettings.
If you end up installing it, simply reboot into safe mode, then head back into cydia and then remove sbsettings.
I am trying hackulo/installous - it should work fine...
update: appsync doesn't work obviously if you have an iPad - OS 3.1 only.
This officially makes the JB half arse. Sure you can diskAid into your root folders, but other than that, completely pointless unless they update the apps for OS 3.2!
#2 update: the following DOES NOT WORK:
* Kirikae
* Backgrounder - works with a respring right afterwards
* emoji
* SBSettings
* AppSync OS 3.1
