Last week, along with the launch of iOS 5 and iCloud, Apple also launched the Tune Store, where you can buy ringtones for $1.29 and alert tones for $0.99.
The goods news is that the simple ringtone hack that was discovered almost four years back still works with the latest version of iTunes, so if you've already purchased the song, you can make a ringtone and an alert tone from it for free.
The hack is based on the fact that iTunes differentiates a song file and a ringtone by the file extension. While we all know that the song file extension was AAC; the file extension for ringtones is "M4R". All you need to do is take an m4a file, which is DRM free and not more than 30 seconds, rename it to m4r and add it to iTunes.
