My iPad is currently running a tethered version of 4.2.1 and I am trying to un jail break it. I thought I could just get the iOS version 4.3 through iTunes and update my iPad and I would be back to an unjail broke state. When I tried, I receive the following message: The iPad "ipad name" could not be updated. An unknown error occurred (3194) So then I did search on unjailbreaking and it said to go into iTunes and press the Restore button, which I did and I received the same 3194 error. Any advice would be greatly appreciated. Thanks!
