Tom let us know that Verizon has officially released OS 22.214.171.1241 for the tour 9630 that will allow the new Push To Talk service to work. The OS version that has been officially release seems to be the same version that was leaked a few days back. If you were one of those waiting for an officially release today is your lucky day or night I should say.
You can download it directly from this link not sure if it has been pushed through desktop manger yet. Let us know if you are able to upgrade through DM.
