Maybe the app you installed from cydia is the problem.Try deleting the app and then try to synch with iTunes.If the synch is successful,the app may be incompatible with iTunes or the current version of iOS and you will have to get along without it.
It was weekillbackground pro. For an unknown reason, it locked my ipad. I had to go in iFile---> Var--->root---> Library--->Lockdown---> (delete this folder). After that, my ipad prompted me to enter my network info and Voila! Afterward, I was able to sync with Itunes.
Don't know why it happened but I'm glad it's over.
