Itunes will not allow me to transfer anything from my computer onto my iphone. When I try it says the iphone can only be synced to one computer and it can sync but will erase info. I did this once and it messed up all my apps. I now have a new laptop, the old computer is gone so what do I do all I want to do is move over some songs and audio books without messings up all my other apps and info.

3GS, iOS 4

    Having similar problem. iTunes Library on my computer (163 songs) but only 33 songs syncs to my iPhone 4. I try to manually move remaining songs but get message "not authorized on this computer". I then Authorize the Computer, but still get the same 'not authorzied' message.

    You can only sync with ONE computer. When you sync to another, it will erase the content and replace with content from the new computer.

    You need to move everything from the old computer to the new one first.

    You can use your backup copy to move everything as well.

    "move remaining songs but get message "not authorized on this computer""

    Are the other songs purchased from another itunes account?


    This may help as well.

    I'm sorry but that is the dumbest thing the iPhone does. The old computer is dead. I can not get the library off it. So now every thing on my iPhone from the old computer plus all items bought on the fly from iPhone will now be lost. For what possible reason would apple do it that way. I can see maybe not getting songs from old computer but to loose ones one your iPhone is just stupid.

    Have you tried contacting Apple? They might be able to de-authorie your old computer so you can authorize it with the new one. Not sure if that helps but it's worth a shot. There also might be programs for your computer that can aide in getting content off your iPhone.

    You can transfer itunes purchases from an iphone.

    Without syncing: File>Transfer Purchases

    You can google for TouchCopy or PhoneView. Third party progams that let you pull stuff off your iphone and onto the computer so that you can then let the iTunes sync process erase the phone without fear. Use at own risk, not supported by Apple.

    General principle to make your life easier: the iPhone should never be the only place where you store stuff.
