Three things about OTA (Over The Air) updates...
1) They are RANDOM. So random that if you bought 2 Bionics the same day, one could get an update days after the other. Back in 2009 when the OG Droid was getting its first update, someone had set up a Google map where you could "stick a pin" showing where and when you got the update. No rhyme or reason at all.
2) They can load in the background. If they do, when you bring your phone up from sleep (i.e., bringing the screen up) it'll say you have an update available. This is assuming you leave your phone on (maybe connected to a charger) all the time.
3) When you check for updates, you are sending a signal to the carrier. The carrier checks your version and IMEI (International Mobile Equipment Identity) number and if you're scheduled to receive it, you'll see a message saying so. This means that if you're scheduled to get an update on June 18th at 3:47am, your phone will say that it's "Up to date" even though others have been getting the update since June 12th.
At this point only the people who are doing the soak test are receiving it. Once the survey is done (maybe by Sunday) the rest of us will be getting
I did add my new IMEI number, maybe an hour before the email from Matt, and have tried all the tricks I know to get the update, but still nothing. What you're saying makes complete sense tho, so I guess I'll just wait around. At least it's not ICS.
