Launch the Listen application, it will sample the music that the iPhone’s mic is hearing and will compare it to a music database to give you back the result.

The application is available from “Installer” on your iPhone or via download from EricaSadun .

Caution: it is very early beta… and it uses network bandwidth… (I don’t know how much…) Users from Switzerland (that means: with cracked iPhones), make sure you are on WiFi… Edge is still very expensive with the Swiss GSM providers…
