is blocked and you need to enter your
PUK (Personal Unblocking Key). Your
PIN and PUK are supplied by AT&T.

PUK and select OK.

Phonelock
You can stop unauthorized use of
your phone. Change the phonelock
code (0000) to any four-to-eight-digit
personal code.
If you select a city, My time zone also
updates the time when daylight saving
time changes.
If Codes do not match appears, you
entered the new PIN incorrectly.
If Wrong PIN appears, followed by
Old PIN:, you entered your old PIN
incorrectly.
It is important that you remember your new
code. If you forget it, you have to take your
phone to your local SonyEricsson retailer.
