Volume Button Extender is a new application tweak in Cydia, which allows users to use the volume controls on their iPhone and iPod Touch, without looking at the device.
Listening to music, press and hold the top volume button for a few seconds, the song skips forward. Press and hold the down volume button, the song will skip back. Let’s say you need to pause your music. Press and hold both up and down buttons, the music will pause. To start playing the music again, press and hold up and down.
Volume Button Extender is available in Cydia, from BigBoss repo, for FREE
