lost everything on ipad2 while downloading iOS5
I began downloading iOS5 by syncing through iTunes. I left the room and came back to a message on my PC which read "Karen's iPad could not be restored. Unknown error occurred." I have tried to restart my iPad but all I get is the picture of a USB connection and the iTunes icon. I assume everything is lost.
Other than cry, what do I do? By the way, I do not have a smart phone and I am 65 years old. I have been losing all of my contacts when entering any contacts manually--a separate problem, I know--but Apple was supposed to work seamlessly.
