I recently upgraded to the iPhone 4s with iCloud. I created the iCloud account and also signed into iTunes on my phone with my current iTunes account. I then purchased some songs from iTunes on my phone along with some ringtones. I plugged my iPhone into my macbook pro to sync the music I had purchased on my iPhone to my computer and vice versa. When I click the music tab and click sync, it says it will delete all the music on my iPhone. The music on my iPhone was purchased with the same iTunes account as on my computer but they won't sync together. How do I mesh my iPhone iTunes purchased songs with my macbook iTunes purchased songs? Both are logged on with the same iTunes account. Thanks so much for your help!
