Delete Pre-installed Apps/Wallpapers/Tones,etc from Nokia Java Phones Without PC

Are you fed up with pre-installed apps/tones/wallpapers/bookmarks of your Nokia java phone and want to delete without help of any PC? 
Here is complete process.
I will guide you step by step.

๏ First we talk about tones/wallpapers/bookmarks. 

For better understanding, I'll guide by example

     Let a pre-installed file in our Gallery in Tones folder is Nokia.aac, and we want to delete it, so first copy any file (image/tone/any other text file) in memory card, and rename it Nokia.aac by MiniCommander or BlueFTP or UC Browser's file manager. Now go to Gallery > Memory card (not My apps > Memory card) and mark Nokia.acc and move it to Tones. (Do not directly move, just mark and move). You will see - "Item already exist". Now go to Tones and go to Nokia.aac, and go to option, you will see delete option highlighted. Do same with wallpapers/other tones also. You can delete multiple files by renaming and mark & moving multiple files at once.

๏ Delete pre-installed apps.

     You need to make backup file of apps and games. Rename backup file with MiniCommander or BlueFTP from .NBF to .zip and open this file. Inside this file, open Java > Collections . There is many folders like cherry_India_private, ovi_private, facebook_private etc. So first copy any file (image/tone/any other text file) in memory card, and rename it cherry_India (do not write cherry_India_private) or as your apps by MiniCommander or BlueFTP or UC Browser's file manager. Go to My apps > Memory card (not Gallery > Memory card) and rename cherry_India to cherry_India.jar. Now mark it and move it to collection or games or where your app exists. (Do not directly move, just mark and move). You will see - "Item already exist". Now go to app and go to option, you will see delete option highlighted. Do same with other apps also. You can delete multiple apps by renaming and mark & moving multiple files at once.
