How can I upgrade my iPhone to iOS 11 after accidentally declining the TOS? The other night I wanted to install iOS 11 on my 6s+ overnight, but I had to accept the Terms of Service to do the installation.  I woke up at 5, had to be up by 5:45, and didn't want to miss out on 45 minutes of sleep. I did not want to start the installation for fear of my alarm not going off due to the update. When I was fumbling around with my phone I accidentally clicked the install option, which took me to the Accept Terms of Service screen. I tried to exit out of that screen, but couldn't. So I hit Decline. Now when I go to Settings -> General -> Software Update, it says my software is up to date (10.3.2). 

How can I fix this situation and upgrade my iOS now?
Just got off the phone with Apple Support:  Do a Forced Restart (hold power button &amp; home button until Apple logo appears then release.)  Now go back to Settings>General>Software Update.
