Q: What is carrier setting update? What does restarting your phone do?
Hey I went to settings and clicked>general>about and it wants me to do a carrier setting update and I want to know what that does? And one other thing when you restart your phone what does it do does it erases messages? History?
Here is a link to some information on Carrier updates and restarthing your iPhone is the same as powering it off and on again. It does not erase or modify data.
