If you just updated to iOS 4.2 on your iPhone, and noticed your music is gone, don’t worry you’re not alone.  The folks over at Tipb have been getting an explosive amount of questions regarding the issue, and have found a fix.

Rest assured, your music is not gone; you just can’t see it.

There is a bug, which prevents the music from being displayed properly, although its pretty scary, especially if you are like me and have 9 or 10 days worth of music on your iPhone, as I said, there is a solution, and it’s a simple fix.

1. Plug in your iPhone to your Mac or PC.
2. When your iPhone pops up on the iTunes side bar look for the content listings underneath it, if they aren’t displayed, click the little triangle on the left.
3. Click on music, pick any song and play it in iTunes.
4. Sync your iPhone.

After the sync, launch the iPod app on your iPhone and all your music should be back, exactly as you left it prior to the update, scared, lonely maybe, but un-touched. I hope this helps, let us know any other problems you are having and we will see what we can do to get ya back on track!
