THIS WILL ALLOW YOU TO LOAD YOUR OWN CUSTOM CARRIER LOGO TO IPHONE 4,
i havnt tried on 4s but it should work on it as well. also you will need to reboot (sometimes twice) for it to take effect when done.

this is not the method i use but it works just the same.

optimize your images if u need and have them ready before you start.

1) Download a program called "Zeppelin" from here

[Only registered and activated users can see links. ]


and install it using iFile or iFunbox. You will not find this in Cydia.
2) Make sure you have given file permission...
Just go to terminal (you can use iFunbox's "SSH terminal" but for this first you need to install "OpenSSH" from Cydia repo) and type in the following:




chmod -R 755 /Library/Zeppelin
chown -R mobile:staff /Library/Zeppelin3)


"Exit" from the terminal

4) Uninstall "Fake Operator" or "Fake Carrier" if you have these already installed.

5) Goto Settings>Zeppelin> and choose any logo you want OR you may add your own logo using iFile or iFunbox

To install your own logos
1. On your local machine create a folder titled for your theme name.

2. Put images in it titled as follows: silver.png for the silver bar, black.png for the black bar, and etched.png for notification center. Make sure to add @2x to the file name if it is a retina icon.
3. Copy this folder from your computer to /Library/Zeppelin

4. Open Settings->Zeppelin and it should appear in the list
5. Enjoy!!
