Rooting Android 4.2.2

view story

http://androidforums.com – Hi there, I have read that Android 4.2.2 is apparently being pushed to Nexus 4 :) Now at the moment my phone is not rooted, if i update to Android 4.2.2 will i be able to root the phone? Also, do i need to always need to flash a custom recovery image to get root access? I thought if i did fastboot oem unlock you would get root? I appreciate if someone could advise what i should do and whether i am on the right lines? (General)
