I just wanted to throw this out there. I went from bone stock .211, unrooted, etc. I side loaded the JB update. I then rooted with the razr blade utilty without a hitch. I then installed Safestrap 3.12, also without a hitch. I then flashed the razr i .apk file. It works flawlessly. Circle widgets asnd launcher is awesome. I then went on to flash Awesome Beats. So, in a nutshell, all of the current files out there will most definetly work on this new update. I'm loving my new phone!!!!
