Unable to turn passcode off/turn off erase data
I have an iPad 4 that I received from my school. I wish to turn the passcode function off, but the option is not available. (Grayed out.) Similarly, the erase data function (that wipes the iPad after 8 incorrect passcode entries) is also grayed out. So I don't have the option of turning that off either.
I have tried searching online and have attempted the following:
Checked for MS Exchange, but I don't have any accounts attached to the iPad yet. Not even an email account.
Checked to disable a VPN, but that isn't enabled at all.
Reset all settings. This didn't work for this, but it did restore my ability to change the "Zoom in on faces" option on the picture frame, which before had been grayed out.
Checked to make sure restrictions weren't enabled.
Some things I haven't tried yet:
updating my iOS to 6.1.3
Do you think these things might work? I keep hearing that the upgrade is not worth it because of the bugs.
I can't seem to find any other suggestions other than a restore, which I've read doesn't work.
Thank you so much for any assistance.
