How to easily get your UDID number without a PC
Had a few issues with the mystery manor game recently and had to contact support they told me to find the UDID through iTunes on the PC and I don't use a PC. I found out though you can go to the AppStore on the PC and search for an app called UDID then you can retrieve your UDID on your iPad without a PC.
I just thought I'd would share my experience incase anybody else runs into the same issue. It's a handy app to have if you complain a lot about a game :)
