Let the hive mind of Engadget get that for you.
"I just switched to Sprint from Verizon about three months ago for the Pre. Then I went for the Hero about a week ago. Now, I miss my hardware keyboard and am thinking about switching to the Moment. I am still able to switch back to Verizon if I want and get the Droid when it arrives. Should I just trade up to the Moment when it comes out, see if I like it, and if not switch to the Droid? Or something else entirely? Help!"
Have .219 on mine and yes there is a VVM icon. I called ATT to ask about it and they are in the process of getting the rights to use and send out provisioning for the service. And you can find beta OS's online....just look for them. I will warn that you can brick your phone if you do it wrong....
About to go with .221 to see if there are any noticeable differences as well.
