Is there an easy way to import AddressBook data into the iPhone Simulator?
Right now my only assumption is to manually modify the SQLite files found in the /Libr
or if your iPhone isn't jailbroken, you can extract the sqlite db from a backup using the shell script here: http://0xced.blogspot.com/2009/01/using-your-own-address-book-in-iphone.html
(note you'll need to change the simulator path it copies it to, as in the current SDK it's a bit different due to the addition of the OS version folder - easiest thing would be to just change it to your home directory and copy manually from there)
