Verizon has rolled out Rev. A, though they have not upgraded the radio in the XV6900. (Check out the above link for the map of current EVDO Markets for Sprint, Verizon and Alltel... you can check and uncheck boxes to view all or just one carrier) I got tired of waiting several months ago and upgraded to the Sprint Radio, then the Bell Radio. I am currently using Whosdaman's Manilla ROM and, after altering the QPST, I get 5 second GPS locks inside and out. In addition, my data connection speed is much, much faster. DSLReports shows my speeds around 1.9 - 2.0 MB while I am tethering. If you want faster data speed (and your market is Rev. A) and/or you want GPS... do the upgrade.
