Met a young guy called Cody Bunea while standing in the queue on Thursday night to get the IPhone.
His company, https://www2.polarbearfarm.com/ is the very first registered iphone apps developers in the world. Great achievement for this small Chch based team. You can download their first app called "telegram" from the app store.
Telegram is personal as calling, un-intrusive as SMS & instant as email. Its a very great way to communicate with other IPhone users in your contact base.
