Among the myriad of fixes that have come with the iPhone 2.1 software update, a nice little feature has been added to the headphones as well.
You can Use the iPhone headphones, or any other third-party headphones that have the click-control on them to jump back one song in your playlist. All you have to do is triple-click the controller and it will jump back to the previous song you were listening to.
So now you can -
click once - to pause
click twice - to move ahead one song
click thrice - to move back one song
You must do these actions quickly or they won’t take.
Thanks to Steve for sending this in.
