A bug has appeared for some after updating their iPhone to iOS 4.2 – iPod libraries disappear! Considering how much music you might be storing on your phone, that could be a major pain. However, it doesn’t affect all iPhones and, better still, people on the Apple forums have already come up with a fix.
If you open the iPod on your iPhone and it claims there is no content:
– Connect it to a computer with iTunes
– Play a song from the iPhone in iTunes
– Eject and restart the iPhone
– Open your iPod library again, and you will see a message about updating the library, after which your media will be back!
I didn’t do this on my personal Mac, but an office PC. You may feel safer using the computer you sync your iPhone with! It’s a very weird bug and, coming so soon after the daylight saving alarm bug, it’s been an unusual experience for Apple users, who aren’t used to this unreliability at all!
