News today points towards a testing build of JDQ39 (Android 4.2.2) for the Verizon Galaxy Nexus. There's even a screenshot floating around XDA (that's it above) that shows the about screen of the phone that's running it. You've got new radios there, which is great news, but the kernel version, and the reported bootloader (PRIMELC03) are old, which is not such great news.
I'm not sure what to think here. Normally I'd shy away from something like this, as a new radio, a new system version, an old kernel, and an unchanged bootloader just doesn't feel right. We all know how easy it is to fake this sort of thing, and even if real, running on one tester's phone doesn't mean a whole lot to everyone else.
I think Verizon is trying to put out a recent version of the firmware for the Galaxy Nexus, I really do. They are close enough partners with Google, that a testing build using an old kernel and bootloader is entirely possible. And new baseband information on the about screen can't be faked with just a build.prop edit. We're going to accept this news at face value, and advise anyone with a Verizon Nexus who is worrying about an update to follow along and see how it unfolds.
I want to believe.
