Another thing that iPhone lacks is the physical music control buttons, sometimes it is extremely frustrating to take out the iphone than go back to iPod to change the track. Well now there is no need to all this anymore, Now you can control the music with the help of default volume control buttons, All you need to install GlovePod from cydia.
This tweak converts your Volume control buttons to Music Control buttons i.e now if you press upper portion of volume button it will change the track and pressing lower half will take you to the previous track. If you keep on holding these buttons, it will act as reverse and forward play of song depending on your portion of hold.
To work your volume buttons as Music Control you need to double-tap home button to get the MediaPlayer on Lock-Screen. You can also Pause the current track by holding the Power button for few seconds.
GlovePod is available on cydia under BigBoss repo for free.
