personally I think it will be just an update to fix what ever issues there might be. Unlocking the bootloader would seem a bit premature to me as I don't think Verizon is going to allow it to begin with. I could be wrong. If I were to predict a bootloader unlock I would say it would be closer to the end of the year. Some time between October thru December if they do it at all. I pray that I am wrong though...I signed up regardless as i hope receiving an update will be an opportunity for the devs to get root some how.
