Had a bit of an adventure with this...

Using Apple's prescribed backup method of my iTunes library (iTunes 8.0 for Windows) to an external hard drive, iTunes went really flaky on me when I copied the libary back to the hard drive after an OS rebuild.

The first thing it did upon synching was to delete all of the apps on my iPhone. I checked the application directory at: C:\Users\Username\Music\iTunes\Mobile Applications, and all of the apps were there. I went into the Itunes applications folder, and the icons were also all present.

Surprisingly, not much info on Google about how to restore apps. What finally ended up working was for me to individually click on each icon, and after being prompted for the directory location of each app, I was back up and running.

Apple, there has to be a better way. What good is a solid backup plan without having an in-place restore option in iTunes?

I imagine it all has to do with their draconian license enforcement policy. But still...

iPhone, Other OS

    This is normal. In regards to iTunes content, an iPhone can be synced with an iTunes library on a single computer only. When syncing an iPhone with an iTunes library on another computer, all iTunes content on the iPhone that was transferred from a different computer will be erased first. Since you did an OS rebuild - which I assume includes erasing your computer's hard drive followed by re-installing the OS, your iPhone detected your computer as a new or different computer even though you transferred the same iTunes library from your computer's backup. The iPhone does not support disk mode, which is the reason for this.

    After you re-installed the OS, did you re-authorize your computer with your iTunes account with iTunes?

    I did not reauthorize until after I had restored the iTunes library from the backup. Should I have reauthorized first, before I did the restore?

    I'm trying to be a good boy and not jailbreak this thing. But man, stuff like this really makes you think...

    I don't believe it makes any difference.

    Please read my previous post regarding the reason for the apps being removed from your iPhone first, which weren't lost. They just needed to be reinstalled along with all other iTunes content which I don't believe jailbreaking an iPhone would prevent.
