Syncing my iPhone 4 deleted all my music I have an iPhone 4 and just just downloaded iTunes on my computer.
I wanted to save all my music to my iTunes so i could later transfer it but i synced it and all my music was deleted. Is there any way i could get it back? 

I have all my music on another iTunes on another computer but that computer is now broken.
No, it's too late. You can't recover music from iPhone...
