The About option is designed
primarily for people who need technical assistance. The About screen
provides virtually everything you need when seeking help, including
detailed information about the phone’s hardware and firmware and
contact information for the technical support department. The About
screen also provides links to the phone’s Terms of Use policy and
privacy policy. You can access the About screen by going to the
Settings screen and tapping About.
Avoid the Reset Button!
The bottom of the About screen contains a
button labeled Reset Your Phone .
Tapping this button permanently erases your data and your apps
(although your phone asks for a final confirmation before doing so).
It’s exceedingly unlikely that you’ll need to use this option, except
perhaps if you’re giving your phone to someone else and want your data
off it.
