Verizon just posted their OS for the Curve today

BlackBerry® Software Updates

However, even though the version number is the same as Sprint's (4.3.0.127), when I installed it and went through Application Loader, it told me that the files were older than the ones that were already on my handset (I used Sprint's OS to install apps onto my Verizon Curve so it also updated the OS files with Sprint).
