I am on AT&T with a jailbroken iPhone 4S and had a custom carrier name using the CleanStatus tweak. Today, I tried to change it. However, it won't change; it has the reception bars right next to the wifi. I have tried using MakeitMine and other carrier name tweaks but I have had no luck. I tried searching but could not find anything that says how to fix it. Any tips and help is greatly appreciated, thanks.
