Can't sign in iTunes

The overwhelming majority of us don't know anything about jail breaking so in a sense we don't know what to tell you anyway.

I don't personally care what someone wants to do with their own device. You bought it with your money and its your choice to do with it as you see fit. I have no problem with that. My point is that I know nothing about it, and I wouldn't want to be responsible for making your situation any worse.

My suggestion would be to restore the iPad and remove the jailbreak.

You're welcome.
