Usually I just drag and drop music(mp3) files into itune when want to add music file into my iPhone 4. But suddenly I can not drag and drop songs in iTunes after updating iTune software to version 10.1. The only way I was able to add songs in iPhone 4 is using Sync up option that I really hate. Finally I found the solution.
Here is the steps
- Connect your iPhone/iPod to iTunes
- Click on Summary tab
- Scroll down to “Options”
- Check “Manually manage music and videos” checkbox
- Click on “Apply” button thats on bottom
- Clicking on “Apply” button will prompt you to erase your iPhone data and sync up again. Note: Please take a back up of your iPhone data before clicking on “Erase and Sync” option otherwise you will loose all your data.
You will be able to drag and drop songs in iTunes.
Hope this helps!!!
