Can some kind soul explain to me how I can edit the sudoers file on my iphone? I would like to add the user "mobile" to it, so that I can do what's necessary to install iPhoneVideorecorder (see http://www.iphonevideorecorder.com/download.html ). When I try to do this sudo chmod 777 /Applications I get the error message "mobile is not in the sudoers file". Any help or suggestions will be highly appreciated. G.
