This does not work. There is not a cellular update- we even went to the phone carrier and they could not fix this! This is Apple. I would like to use my old phone like an iPod- however after a factory reset, it still will not let me in the phone! Says to contact apple support. Someone needs to fix this please- we pay a lot of money for these phones, they should last longer than they do!

So you are also having a problem with a carrier update like the Original Poster? Can you provide more details regarding what model phone you have, what version of iOS you are running, are you getting the same message that you need a carrier update, etc?
