App Review: Fake Operator [Cydia Store] How to change your carrier logo on 4.2.1
So now after using our Greenpois0n RC5 tutorial, I have realized that I can no longer use "Make It Mine" to change the carrier logo on my iPhone as it is not supported beyond 4.1 Fortunately there is a solution. There is a similar application called Fake Operator which allows you to change your carrier logo from your iPhone settings instead of through an application the way MIM did.
First open Cydia and search for "Fake Operator" this is a package available from the default sources so no need to add a new source.
Now that you have Fake Operator installed go to your "Settings" application and click on Fake Operator
Once you've opened Fake Operator settings just switch the toggle to"On" and set whatever name you would like to be displayed in place of your carrier.
That's it, you should now have a custom carrier logo!
