I received 2.2 about a month ago? I went into Verizon and asked about updating and I was told it would be anyday at the time (2 months ago or so). About a month later i got the update. My phone was buggin out so I took it in and the service employee told me that they were sending out the update in batches to people so some had it already at that point and others did not. I'd imagine by now that most would have it. I played around with the Droid X but I don't know about the firmware.
I have the original droid, kinda wish I had the Droid 2.
I'm pretty sure all the Droid 2's started out with 2.2.
