The Tuner App was built by one of the original Nullsoft developers.
It bears no resemblence to the modern hoi polloi who line up for SEO clicks behind the terms “Tuner” + “iOS”.

Tuner was a lovely piece of software. Back when it was called iRadio, I went so far as to crack my 1.x iTouch to get it installed.
5 months later, there jailbreaking was no longer necessary. An official release of Tuner in the App Store made the whole setup a lot more sanitized.
I believe it was a 32-bit App, and it never achieved a rewrite / upgrade.
