This is excellent news of course, despite being ridiculously late arriving.
I have been running the leaked Motorola 4.1.1 JRO03H build since it dropped last June so I certainly hope its a newer build than that one.
It's actually quite stable despite some annoyances like limiting write access to the sdcard and keyboard misbehavior persisting.
The radios perform very well in this build so it will be interesting to see what changes, if any, appear assuming a new baseband is included.
There's no discussion. It'll be newer. It'll either be JZO54K like Wi-Fi or a newer build of 4.1.2 that we haven't seen yet (unlikely). I'm sure there will at least be a new CDMA baseband if not a new LTE baseband as well. I say this because the original leaker of that 4.1.1/JRO03H build had a newer CDMA baseband in his screenshot that no one had ever seen before (03.1A.66SP), but his LTE baseband was the same as the IMM76L ICS build.
Speaking of that leaked 4.1.1/JRO03H build, it looks like it was just the Wi-Fi build with the LTE drivers dropped in for testing.
The leaker claimed that Verizon had signed off on it but I don't buy it for two reasons. First, it was never released. Second, that build has a major DRM bug. Google Play Movies won't stream content when using that build because either the DRM keys are hosed or the build itself has something turned on that makes the app think the ROM is rooted.
As for how he got it, he said his own Xoom had the build installed by Motorola development. That much I do believe due to the fact that he had a CDMA baseband that no one else had ever seen.
