But can you unlock your bootloader after taking the 4.3 update, or just root? If you can unlock a 4.3 bootloader, that's interesting, because I've heard that it isn't currently do-able? Having root access and an unlocked bootloader are two different things...you can't successfully flash a new ROM unless you have an unlocked bootloader, although you can do a certain amount of playing around if you have root access with a locked bootloader.
