For a long time, the only way to alter the boring carrier logo on your iPhone or iPad has been to Jailbreak your device, an action that can be a real hassle. However, there is a way to alter the carrier logo without Jailbreaking, and this is through the app for Mac called Carrier Editor.
To load a logo of your choice, follow these steps.
Step 1: Download the Carrier Editor application from uhelios. Connect your iDevice via USB to your Mac. Open the Application.
Step 2: Carrier Editor will first need your Carrier Version Number, which can be found through going into the settings app, then in General, and then into About. You’ll need to enter the number into the Carrier Editor app as per the instructions.
Step 3: You will then have to select your device and carrier from the next screen. If your carrier is not displayed here, then you won’t be able to complete this process.
Step 4: Drag any logos you want into the space on the next screen. If you don’t have any of your own, there is a variety of pre prepared ones in the .dmg folder downloaded with the app. Carrier Editor will not completely delete your original carrier logo, it creates a file of the original, which will be located on your desktop.
Step 5: Open iTunes and hold the Option key while clicking the “Restore iPhone/iPad” button. You will then be able to open the newly created file, and this will put it on the device. If it does not show up immediately, restart your device, and it should be ready.
