On top of this, I added a live to remove /system/etc/install-recovery.sh. This is because whenever the phone booted, it removed CWM, and thats definitely not something we wanted it to do! So all is well. This file (RAZRiRoot2.zip) is included in the new Jellybean Vodafone (FR) Homemade fastboot of mine also. Its less automated for rooting since the boot.img method is weird with Windows drivers...
Anyway, here we go.
Unlocked Bootloader on Jellybean
Flash this in CWM to root any Jellybean RAZR i firmware.
