An anonymous reader writes "Cyanogenmod is soon to have a better permissions systems, allowing its users to deny certain permissions to the applications they install. Users are warned that enabling this feature on the nightly build may cause applications to crash or 'force close', but a new dialog allows them to easily return the permissions to stock if they wish. Hopefully Google implements a system similar to this very soon."
