A bit of trouble updating an iPod Touch to iOS 4.0

I had my doubts about the wisdom of updating the firmware of my iPod Touch to 4.0 from 3.1.3 and in retrospect I was right.

It all seemed to be going well at first but what was probably intended to be the final stage crashed when doing the restore of my content.

None of the music was there but the apps were. However none of the added apps worked.

A re-sync got the music back but still no working apps. The music was in it's full 256kb/s glory not the 128kb/s AAC+ which I had previously squashed it to.

Perhaps this was part of the trouble, the previous back up didn't fit in my 8GB iPod Touch with a film I had on it.

I followed the advice on the Apple website about de-authorising and re-authorising. I then deleted, re-downloaded and synced the apps.

Finally, in desparation I reset the iPod Touch. Then, after re-syncing it all worked. It also came up with a new background on the home screen.

Others might have had more trouble getting their touch to work again.
