Not sure how far out a full on roll out is, but at least one person has received a new (on top of ICS) 100 MB update that appears to enable the global capabilities of the Rezound. He has posted a couple screenshots of his phone while it was receiving the OTA update, as well as a pic of his phone in the bootloader showing the new Hboot version as well as the new radios. He also posted up the actual files pulled from his phone (no, I can't tell you where, TOS and all that) that people more capable than I am have looked through and are saying this is real. Won't know what other bug fixes may be incorporated until Verizon posts an official change-log but, if you have been waiting for the global capabilities to be enabled, you shouldn't be waiting much longer. Also, this could be part of a soak test, so the official OTA may be a couple weeks out.
To recap:
Global capabilities enabled
New Hboot version
May be other bug fixes, but it isn't known if or what they may be
Not yet pushing to the masses, but should be soon
