My iPhone 4S is running the current IOS (5.1.1) on the Verizon network. But when I went to sync it, iTunes tells me that it wants to run a An update to the carrier settings for your iPhone is available. Would you like to download it now? What is strange about this is the iTunes app says Your iPhone is up to date I normally wait till I hear on the rumor-mill what an update is doing. But I have not heard a peep about this one. Anyone got any ideas as to what this is?
