There's a new firmware out for the Droid X, but here's what happened....
The units that were given out at the NY event a few weeks ago had firmware 1.13.514. This was a release candidate firmware and it didn't include the Need for Speed Shift game. My source at Motorola said the final shipping firmware would be .516 on the retail phones. Yesterday I had to send this demo unit to my coworker, as he's going to be doing a comparison with it and the EVO and iPhone4. Since that left me without a Droid X here to work on, I was able to have another one sent out, that I got today.
This one does have the .516 firmware and the Need for Speed Shift game. After a few minutes of having it on, a screen popped up saying that it wanted to download and install a newer firmware 1.13.604 that was 16.5MB. It had a place to click for release notes, but it was blank. So I downloaded it, and then looked for the update.zip file, but it wasn't on the SD card, nor could I find it on the phone (it may have been in the /data directory, but you can view hidden files in there). After I installed the update, the only change I've seen so far is that Kindle app is now on the phone (but there could be internal fixes/updates).
Here's the new version info:
Software: (was .516)
Baseband version: (was .04P)
So those of you that are going to by the Droid X, it will most likely have the .516 firmware, but you'll have an update to .604. Maybe by then will know if there was any other changes besides adding the Kindle app.
