Are the messages going from iPhone to iPhone/Touch???
Search the App Store for "WhatsApp"

My sister doesnt have an iPhone![]()
Im sure it's iPod Touch compatible also. But failing that, i'd just email, its just as easy and its free.

My vote would be for FishText (http://fishtext.com/), lets you text any number in the world for pennies - I believe its either 1.3p or 2p per text depending on which network in Australia you're texting.
Here's a link to the app http://linktoapp.com/fishtext
Thanks, using this atm
