Accidentally cancelled update to 2.3 this morning; how do I get it back? I woke up 2 hours ago and there was the message on my phone (HTC DROID Incredible) that a new update was available and that my phone would restart to download and install the update and of course I click the "Install" button, but the way I was holding my phone was odd and my palm accidentally hit the "Cancel" button as it was counting down to restart the phone and it only got down to 5. Now the update seems to have disappeared. When I go into Settings &gt; About phone &gt; System updates my phone says that my system is already up to date. I also tried doing that *#*#CHECKIN#*#* thing which did not do anything (it said I was checked in but the update didn't come back). I thought the update would have automatically popped back up after 30 minutes but it's been two hours and my phone seems to have no trace that the update was even sent to my phone.
Others are reporting similar issues.  Is your build number 4.06, 4.08 or other?  I would suspect that if you missed the initial rollout you'll have to wait a bit, since they would want to do it gradually and not overload the network.  You might get prompted again later or they might enable manual upgrades at some point.

Verizon says you can update over Wi-Fi, though again it looks to be an automatic thing rather than manual, but maybe you'll get a second notification if you connect to Wi-Fi.
