While trying to update my iPad2, I get the message:
An error occurred while backing up this iPad(-5000). Would you like to continue to update this iPad?
Continuing will result in the loss of all content in this iPad.
ITunes is 10.5.3. I'm trying to update the iPad rom 4.3.1 to 5.
What should I do? Should I cancel and try again or must I lose "all content"? Any help would be appreciated.
