Yep, I have. Got it a few weeks ago now. If it helps, I'm SIM only on O2 Simplicity Unlimited and bought the phone outright from O2, though it's still O2 branded. I wasn't notified about the update, I had to check for it. That said, I checked for the update about an hour or so after it became available by chance, so maybe it was too early to be notified. I've heard lots of other O2 820 owners say they haven't received the update. Don't know why I got mine. I thought I'd be last in line not being on a phone contract. The only other thing that I can add was that my data connection was via WiFi at the time. The update still took half an hour. Do they only tell you about the update only if you're using WiFi, because the download would take an age and bust you're data otherwise. I don't know. If it's any consolation, as far as I can see, you're missing diddly squat!
