actually, given the way apple apps work and their walled off access within the filesystem, they can't grab this kind of data nor access data outside their fenced in area. not without the user knowing about it. access to the address book, calendar, even your ipod playlists all has to go through approved apple api's.
what that app did was open a socks proxy, fairly standard port connection. all the code for the proxy was contained within the application itself.
