Change mediaplayer skins in a Nokia cell phones

Change mediaplayer skins in a Nokia cell phones: "Why
Accessing the phone memory will shoe you the system files of a cell phone for playing .
e.g. in a S40 cellphone, the media player has a default theme which you can't change but with this you can change it, backup the original java apps etc.

How
The original PC suite application doesn't shows the system files so we will use Oxy Cube for this."
