Once jailbroken, you can customize your iOS device in a million different ways. For example, you might want to change your carrier logo. You can use Photoshop to create your own logo files, SSH into the device, replace the photos, re-do them a few times until you get it right, or you can install a simple and free tweak called Zeppelin.
Zeppelin comes packed with logos that you can choose from, but the best part is that if you don’t like the default logos or get bored with them, the various repos in Cydia offer hundreds if not thousands of custom logos that you can download and use.
If you decide you want to change your carrier logo, Zeppelin is available for free in Cydia via ModMyi repo
