(Or, How to sync an iPhone with one computer and manually manage music and videos on another).
Because I do most of my music listening at work and my Calendar/Address book are kept in Outlook I have my iPhone setup to sync with my office PC. When I’m at home however I find I also want to put music/podcasts/videos on my iPhone for the weekend or trips.
Normally it’s only possible to sync an iPhone with one computer. If you try to use a second computer you get the warning below that "the iPhone XXX is synced with another iTunes library. Do you want to erase this iPhone and sync with this iTunes library"?
However, I’ve found an easy fix for this. In the instructions below I’ll show how to modify any iTunes Library so it can also be synced with your iPhone. You can then either manually manage your iPhone on a second computer, or sync different data on different machines (E.g. Music at home, Contacts/Calendar at work).
The instructions below use the example of modifying the iTunes library on my home Mac to work with my existing iPhone/PC setup. If your existing library is on a Mac, or both machines are of the same type, then the steps are identical.
