So after setting up Google Apps for a small business, I've been amazed at how it fills the role as a simpler Active Directory.
However, how can I access these contacts on a mobile phone, e.g.,an iPhone? As far as I can tell, it doesn't sync to my phone.

It seems the contacts doesn't sync, but you should be able search them from your iPhone. This means you have to be on-line to find them. From support.google.com:
This presumes you have set up your Google Apps for Work/.edu/.gov account as an Exchange Active Sync account on your iPhone. See Google's documentation for that.
I just tested this for myself. I'm able to search the global contacts, and for any result I can choose to add it to my local address book, or update an existing contact.
