I keep getting a popup saying there is an update to my carrier settings. I've been getting it for quite some time now and just always ignore it. Does anyone know exactly what these settings are updating? And is it safe to update if I'm jailbroken? Sorry if that's a silly question, I just don't want to risk messing up my jailbreak as it is a hassle to go through with the restore/jailbreak process all over again because it takes AGES to load all my music back onto my phone.
