Have you guys just been checking the ota on your phone and not the Motorola website?
Try going to the Motorola website, click support, then software update and select the atrix. Download the update flasher program then try through there. That's how I got mine.
Last night I kept trying the ota on the phone and kept getting the message that my phone was current, then tried this rout and got my update right away, though I couldn't install it until this morning because I was low on battery.
I tried that, but it said my phone was up to date.
I'm not sure if I already installed it or not because I just updated my phone yesterday. I just bought the Atrix yesterday too. How do I check to see if it's already installed?
