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.
