If you are looking for a retro radio for your iPhone, this apps will satisfy your need. The Old Style Radio by Alexandr Balyberdin come with retro old school interface, user friendly and simple interface. You can either rotate the rotating dial to turn to the next online radio according to the music genre. And the sound effect of searching radio station while not tuning to any radio station makes the apps look so real. Cool.
But one thing that annoy me is, how to turn off this radio?
You can download it from the apps store.
