I watched the latest Daniel Rubino and Zac Bowden podcast (video live stream on YouTube) yesterday - not yet posted - and the second segment was about the Elite x3

WELL, Dan has a Elite x3 that he ALSO tried inserting a Verizon SIM and his ALSO "connected for about 2 minutes and then dropped".
SO ... it appears that the "CDMA radio IS on-board the EXISTING MODEL" BUT NEEDS a "firmware upgrade" to operate on the Verizon Network. (we all have read that Verizon "currently and historically separates" the CDMA for "voice" and the LTE Band 13 for "Data" traffic.
Once again, CAN the LTE Band 13 radio be enabled because it is also onboard existing units in the wild?
NOW, the $64,000 question IS ... WILL Verizon "allow activation and firmware upgrade to EXISTING HP Elite x3's - OR - REQUIRE PURCHASE of a new HP Elite x3?
