Does any one have any idea as to what is stopping this? Is it a url or maybe a port stopping the iPad verifying with Apple? I have been though this document http://support.apple.com/kb/TS3297 and unblocked all the urls and all the single ports (not the big range of ports though)
I'd call your apple care support number get some help.
If you want to diagnos it your self, I'd look in the logs.
I've got an old mac, but yours is probably similar.
Your blockage could be by some institutions router, but your talked to them to open other ports. The router should/may have logs too.
blue apple > system preferences... > sharing > firewall tab
Go click on advanced. Enable loging.
After failure, come back to this dropdown and look at logs.
Look in the log and see what ports were block. I'm not a export on these things. Some ports are dynamic and will cange from boot to boot. Don't know about your situation. A blocked port, 1009, is highlighted in blue.
Thanks for this rccharles unfortunatley this is on the iPad iOS or OSX so I'm not sure if these options are on the iPad however I think your right about contacting apple care support it think at this stage it the only way forward.
I got confused over what you are doing.
I did find apps in the app store to read console logs.
I do not know if you will get the information you need with either of these apps. On my mac the info is in the ipfw log, stands for something like iternet protocol firewall log.
Well I got the following from the free log app, I'm not sure if it even relates to the problem but I opened the app tried a iOS update which failed and went back to the app. It had the following:
Wed May 15 15:25:31 2013 Preferences com.apple.Preferences <Warning>:void loadAPTableCellImages(): loading images
Wed May 15 15:25:33 2013 Preferences com.apple.Preferences <Warning>:-[APSettingsController specifiers]: Raven: _canForget(0), _canSetAutoJoin(1), _canSetAutoLogin(0)

Not sure what I can get from this tho
