Shortwave on an iPhone ?

All you have to do is build a quadrature sampling detector

Stan Horzepa: "[A] software defined radio (SDR) application for the Apple iPhone, iPod touch and iPad called iSDR. It is a portable software-defined radio receiver designed for experimenters, shortwave listeners and Amateur Radio operators -- and it is free! A caveat: receiving live on-the-air signals with iSDR requires purchasing or constructing a quadrature sampling detector (QSD) RF front-end device that connects between an antenna and the microphone input jack of the iPhone, iPod or iPad."
