Certain settings are greyed out after updating to iOS 6
Hello,
I can't seem to find anyone else with this problem and so I thought I'd try my luck here. After updating my iPhone 4 to iOS 6, if I go to General-> Settings, my iCloud is greyed out, along with the switch to turn on iMessages, Facetime is greyed out along with the Facebook & Twitter.
The only restrictions on my phone is being unable to delete my profile. I have my phone managed with the Casper Suite, but I manage it myself and do not have any policies on it.
I did have the issue where I "couldn't connect to the iTunes store" but I fixed that (probably not related, but just in case).
I have tried doing a hard reset on my phone twice, and that has not helped my issue. I realize I could restore my phone, but I really don't want to lose the data on some of my apps (including some things that were purchased in the apps). Any other ideas?
TL;DR: Facetime, iMessages, iCloud, Facebook, and Twitter are all greyed out under my settings after updating to iOS 6, and I don't know how to "un-grey" them.
iPhone 4, iOS 6
