I just picked up the JF_Updater, and while I am rc33 rooted, the updater said there is the rc33 1.42 update available. While I would like to update to this, JF recommends backing up with Nandroid. Now, I have not backed up using Nandroid. How easy is it up backup with Nandroid? What are the chances of bricking the phone? Is 1.42 stable enough that I can take the chance without backing up? Should I just wait for jf 1.5? Any help and advice would be appreciated.
