OK, so I was initially having a problem with my new D3 VPN connection not updating routes, but that turned out to be an issue with busybox.
However, after correcting that, still no dice over 3g, but WiFi connection worked fine: http://forum.xda-developers.com/show....php?t=1440481

So, I called Verizon Tech Support, they enabled General IP (after contacting my company's authorized account holder) and sure enough, issue resolved.
So, Verizon was indeed blocking needed traffic over 3g.
