How do i sync the iphone with itunes on different computers without erasing anything currently on the iphone?

iTunes

1. Select "Disable automatic syncing for all iPhones" under Edit - Preferences -iPhone in the iTunes menu.

2. Uncheck "Automatically sync when this iPhone is connected" in the Summary tab of iTunes.

3. Check "Only sync checked items" in the same tab.

4. On the computer you want to sync contacts and calendar, check the corresponding boxes in the Info tab. *UNCHECK* everything else in the MUSIC, PHOTOS, PODCASTS and VIDEO tabs.

5. Sync your iPhone with this computer *first*.

6. On your other computer, follow the same steps above (1, 2 and 3). Then, *UNCHECK* everything in the INFO tab, and check everything else on the other tabs.

7. When you sync with this second computer, you may get a message that the iPhone has already been synced with another computer, and that the media library will be deleted.

8. Sync. Then you can sync on both computers and each will sync what is checked and not overwrite the rest.

1. Upgrade to the latest version of iTunes (this will make the transition easier as the new machine will also be running the same version of iTunes)
2. Sync iPhone on the computer for the last time
3. Deauthorize iTunes on the computer
4. Copy the entire My Music folder from the computer to your other computer
5. Install the latest version of iTunes on this second computer

There is a really handy way to Sync iPhone with different computers.
It worked extremely well.

Normally iTunes will limit your syncing of the iPhone from one library located in one place. Trying to sync with another library results in content on the iPhone being wiped first.
