How do I sync my iPhone with two computers?

Question

I have some music on my iPhone. But I got a new computer and have some new music on that. How do I get the new music on the phone without it erasing the old music. Everytime I try to put the new music on, it erases the old music saying it cannot sync with two computers. The only way I can think of is to use CDs to transfer the music. But I'd really rather not do that if possible. Is there another way?

Answer 1

you will need to have a 3rd party tool to help you copy songs in your ipod touch/iphone to computer as itunes blocks the ipod-to-computer transfer, here is a review of top 5 ipod touch/iphone copying softwares.

Answer 2

itune blocks this function since itune is the tool with one way to transfer files from itune to iPhone. you must utilize other tools to achieve that. There're couple of tools for transferring the files between iPhone and computer (for backup)depends on your demands, e.g transfer only songs/videos, transfer photos etc. You can have a look of below review site, hope it useful.
