i have a rooted sprint S3. i now have a message saying that i have a system update available. i selected to restart and install. when it restarted it was in cwm and asked if i wanted to "install an untrusted zip file"... i chose no and restart. here are the questions... am i able to install system updates? are there any updates i should not install? is this "untrusted update" just a warning from cwm? sorry if this is the umpteenth time you have had to answer this G!
