Last week I spent $15 on iToner, which allows you to turn MP3 files into custom ring tones for your iPhone. I’m not a fan of ring tones, but I thought that iToner was a cool hack, so I went ahead and bought it. Unfortunately, Apple killed it with this week’s iTunes 7.4. Ambrosia is promising a fix, so we’ll see what happens. I hope Apple didn’t kill it deliberately, but it wouldn’t surprise me if they did.
