Cant authorise ipad on itunes ipad is now empty!!?

I updated my ipad to firmware 4.3.3.. My partner came along and tried to jailbreak it using the program "spirit"... He assumed the jailbreaking didnt work for some reason.. He used the ipad and turned it completey off.. I went to use it the next morning and the icon came up with the white usb cord and told me to connect it to itunes.. I assume since it ws jailbroken and turned off u have to restore it to work again.. Ive been told once u jailbreak it and it turns off it will never turn back on.. Anyway my partner plugged it into itunes and it says "sorry we we're unable to authorise the ipad try agian latr' or something along those lines.. So now the ipad is empty cant turn it on past the page that says connect to itunes.. Its not authorising or being activated in the computer so that means i cant even get to the summary page to restore it.. What can i do?? Thanks
