That's the issue. When I couldn't find YouTube in its usual spot, I did the Spotlight screen search. Nothing. Then I checked my son's iPad, also recently updated under 10.6.3. No YouTube there, either. Wife had not updated HER iPad in quite some time, and yes, she had the YouTube app.
I didn't check Restrictions on any of the iPads, but then I didn't restrict YouTube. If it got restricted, then it is something that iTunes did, not me, not my son.
And then there is the issue of the corrupted backup. I didn't do that, either. There IS one other detail: I'm running the system that shall not be named (yet, and yes, it is legit), and perhaps that somehow affected iTunes' behaviors. It has certainly caused odd behaviors in other programs I use.
But the point of my original post is, can I restore the iPad backups from Time Machine? If so, how? Any help would be greatly appreciated.
In the meantime, I'll check my son's iPad to see if YouTube has been restricted.
