What verizon store were you at that had a Droid X that you could use? They dont come out till July 15th. I've been to each vzw store here and looked for them, not a single one of them had them yet, not even a demo model.
No one can figure out why, but some stores and even users have been getting early Droid X shipments.
(Apparently many companies that do business with Verizon are getting a free Droid X sent to them to play with as well.)
