Read to pull out what little hair I have left. I can't get it to upgrade from version 4.3.3 to version 5.01. I have installed the newest version of iTunes and have tried it on both my Win7 x64 desktop and WinXP notebook with no luck. I keep getting the error code 3194 that says: "The ipad count not be restored an unknown error occurred 3194" This ipad had been running a jail broken version of 4.3.3 prior to my starting the process. I downloaded a clean 4.3.3 and restored that wiping out everything on the unit and it run fine on that. Even things like cable visions optimumapp work fine and they would not run when jail broken, yet I still cannot get iTunes to upgrade this. What next????
