unify / ununify iPod on your iDevice

This is a simple step-by-step tutorial on how to unify / ununify iPod (music and videos) on your iDevice.
1-open iFile , iFunbox , WinSCP or Cyberduck
2- navigate to /system/library/coreservices/springboard.app/[plist for iDevice]*
3-find the unified-ipod code
4- change the true to false or the false to true**

* iDevices have a different plist in the springboard.app for iPhone 3G it is the N82AP.plist and for iPhone 3GS it is the N88AP.plist , if you own another device then google the plist which your device depends on.

** if the field is set to true then you will only have the iPod app, if it is set to false then you will have a music and a videos app.
