I know. It really stinks that Apple didn’t allow us to use custom ringtones in the first place, but that hasn’t stopped the hacking community from figuring out a way for themselves. After some stumbling, a little bumbling, and possibly a pinch of fumbling, a definitive guide has finally been produced that will walk you through the entire custom ringtone process.
Available at Hack the iPhone, this step-by-step guide comes complete with photos and screenshots, so you can be sure that you’re doing the right thing. Obviously, they take no responsibility for any goofs that you may do and if the net result is a bricked iPhone, well that’s your problem too.
We should warn you, though, that the hacking process depicted in that guide is not exactly a point-and-click solution, as it involves two different hacking tools, Apple’s iPhone Software Restore file, and the Terminal.
