Guide to speed up iPod Touch is below

?
Hello everyone.
I’m searching for a detailed list of everything unnecessary on the iPod Touch 2G 4.2.1
I’ve deleted all unnecessary language packs, unused launch daemons, unnecessary icon shadows from /System/Library/CoreServices/SpringBoard.app, all -hd files from applications I’ve downloaded along with @2x files, and I’ve disabled spotlight.

I’m going through the System files now wondering which files and folders my iPod Touch doesn’t need. I know the majority of files in /System aren’t needed to run my device. Most of them in that directory is for the iPhone anyways. I’m searching for a detailed list of only the files needed for iPod Touch 2G.

Please don’t tell me to downgrade, overclock it, vm (virtual memory), speed up animations, nor’ buy a new iDevice.

All other ideas on how to speed the performance and improve the ram is greatly appreciated.

Deleting @2x images:
To delete @2x images, ssh or use iFile or some other program to access your iPod files and use the search option. Search in the directory /
The search may take awhile depending on the amount of memory used. Once you found all of the images, delete them all.
Alternatively, you can download Remove Retina from our lovely insanelyi repo.
If this alternative method is done, then READ THE DESCRIPTION FOR IT! THE ALTERNATIVE METHOD IS FOR EXPERIENCED USERS!
If you don’t know how to use Mobile Terminal or don’t know what that is, do not do the alternative method.
The repo is repo.insanelyi.com

Deleting -hd files:
Do the same thing for @2x, but search -hd.
Search in the directory /
They’re may be other files besides images. Delete them all as well.

Deleting unused system apps:
Ssh or use iFile or some other program to access your iPod files and go to /var/stash/Applications.pwn and you’ll see a list of all undeletable apps.
Be sure to not delete anything you use or don’t know what it’s for.
Deleting apps such Nike, Stocks, Weather are also good for a little boost.

Deleting language packs:
Ssh or use iFile or some other program to access your iPod files and serach for .lproj in the directory /
Delete all .lproj EXCEPT the languages you are using. Example: English users should keep all files that are named en.lproj and English.lproj.
Alternatively, you can download lang2ez from our lovely insanelyi repo.
If this alternative method is done, then READ THE DESCRIPTION FOR IT! THE ALTERNATIVE METHOD IS FOR EXPERIENCED USERS!
If you don’t know how to use Mobile Terminal or don’t know what that is, do not do the alternative method.
The repo is repo.insanelyi.com

Deleting launchdeamons:
A good forum has been posted on our website about deleting launchdeamons.
How to delete these and what they are can all be found here.

Editing the N72AP.plist:
The file can be found at this directory /System/Libarary/CoreServices/Springboard.app/N72AP.plist
This file could be named differently depending on what iDevice and iOs your using.
Here you can disable and enable features not intended for a iPod Touch 2G. (ie: Multitasking, etc.)
Here is everything I disabled. (Most of these may be disabled by default)

1)Bluetooth
2)gas-gauge-battery
3)Homescreen-wallpaper
4)hw-snapshots-need-purplegfx
5)location-services
6)microphone
7)Multitasking
8)Nike-iPod
9)Piezo-clicker

This is what my N72AP.plist file is configured to. You can just copy the green text below and save it into the directory above with the .plist extension.

Tweak: You can also change your iPod text in the top left of your screen to whatever you like by going into device-name and editing the text.

Removing unneeded mobile substrate addons:
It may be a good idea to go into your Cydia packages and delete things you don’t use anymore or don’t find useful.
Most mobile substrate addons will eat away at your ram, so unistalling packages wouldn’t be a bad thing at all.
To do this, just go to your Cydia app and unistall everything you don’t use anymore. (Best if you change the viewing of packages to expert)
Examples of substrate addons would be sandcastle, libhide, Activator, PreferenceLoader, Winterboard, ZAdBlocker, Etc.

(Advanced) Running sysclean script:
This is a script designed by brc0703.
1) Add the insanelyi repo which is repo.insanelyi.com
2) Download Mobile Terminal (NEW) from the insanelyi repo.
3) Download sysclean from the insanelyi repo, as well.
4) Open Mobile Terminal and type su and press return.
5) It should say password, type alpine (NOTE: When typing in alpine, the characters won’t be shown, but it’s ok)
6) Press return and you should be able to run as root. (It should pop up with root #)
7) Simply type in sysclean and press return.
8) Let the script do it’s magic!~
9) After the script has ran successfully, you have the option to remove it via Cydia.

Results after the guide:
Your iPod Touch should be faster then ever before!~
Of course, that’s stating the obvious or else you would of never even touched the guide.

If anyone has any other suggestions, please be sure to reply!~
