You can always check under 'System updates' in settings to see if there's any update waiting for you. If you want to check which update/version you're on, go to 'System version' under 'About phone'.
21.21.15 was the current version until today, where the 21.44.8 update (simultaneous voice/data, Advanced Calling) has started to drop. Not everyone is receiving this update at the same time; it may take a day or so for some people.
Gotcha, not sure what's going on there. Maybe the update will come back later? I wonder if VZW or Motorola would be able to tell you anything. Sorry, I don't have a lot of tech expertise, that's about all I got, except...
Factory reset is always there as a last resort - not guaranteed but it cures a lot of ills. That's obviously a pain though, hope it doesn't have to come to that.
chatted with motorola. they said I should get pinged again. I thought it was sort of weird that 'searching' for updates wont find the one that just tried to update...
