I have recently ventured into syncing my iPhone to multiple computers. I use my home computer to sync pictures, music, videos and contacts to my iPhone; while I use my office computer to sync calendar information. I had originally planned on using my office computer to sync all of my contacts to my iPhone, but then I realized that I typically use my phone for personal use and don’t use it for business that often. Besides, it’s much easier to find contacts in a list of 150 rather than a list of 400.
Anyways, after successfully syncing to my home computer multiple times, I finally decided to bring a cable into my office and sync the iPhone to my office computer as well. Upon plugging it in, I was prompted with this message:
The information on the iPhone is synced with another user account. Do you want to sync this iPhone with the information from this user account instead?
“Merge Info” merges the information on this iPhone with the information from this user account.
“Replace Info” replaces the information on this iPhone with the information from this user account.
Its nice that Apple gives you the option of how you want to handle data from each computer – Either Merge Info or Replace Info. Plus its nice that it lets you pick and choose which information you want to sync from each computer, and the location that you want to sync from (for pictures, music and videos).
