Sending Data between an iPhone and iPad?

Is it possible to use 开发者_开发技巧an iPhone to connect and send data to a iPad? And how would you go about doing this?

Could you open a socket and connect to the iPad with its IP address? (iPads/iPhones have an ip address right?) Go easy I'm new to network programming...

Thanks!
