I believe the "official" unlock may happen in time. It wouldn't surprise me in the least bit if LG adopted the same practices as HTC in that regard. With that said, it's not something Verizon will ever allow on their devices. In the past, we may have gotten lucky. Now, we only have that option if Verizon and the manufacturers offer us a "Developer" or Google Experience edition. Personal advice would be to lock down your phone via Titanium Backup concerning OTAs, regardless of how enticing they may be, and wait for the Dev community to release their method.
