How do I transfer music from my old 3gs to my new iphone4?
I have just bought a new iPhone 4 and a new iMac. I have an older 3gs that was set up on another computer which I don't have access to anymore. Can I or is there a way to transfer all of my songs, photo's etc.. I have purchased on my 3gs to my new iPhone4?
You will have to restore the backup you made of your iTunes library on your old computer to your new iMac.
The iPhone is not a backup device. The data (music, video, etc.) lives on your computer and is 'loaned' to the iPhone so you can take it with you.
If you did not keep a backup of your old computer before you disposed of it/sold it/ got it stolen, etc. then you may be able to find a 3rd party application that will allow you to extract your music. This is not sanctioned by Apple.
