I can't use my phone because it keeps bringing up a window that says Carrier Settings Update. New settings are available. Would you like to update now? Whether I pick not now or update it doesn't let me out of the window!!!!!!!!!!!!! help
Shut the phone off by pressing the power and home button at the same time until the screen goes black, once the screen goes black release the two buttons and turn your phone on again and see if it comes up again or not.
