DO NOT uninstall Rocky Racoon. Rocky Racoon is the jailbreak exploit that is used by Absinthe, even if you did not untether a tethered jailbreak, Rocky Racoon will still be installed since it is necessary for the jailbreak to function. If you are able to uninstall it, it will mess up your jailbreak and probably require you to restore. (This goes for ALL devices, even 4S, iPad2 and iPad3).
