Software

Software update, how?

I have been asked a lot about how to update the software in Sony phones.
The easiest thing to do is to go to the nearest Sony
dealer and make him do it for you. Just remember that it is supposed to
be free (a receipt is requiet) so don't let him tell you anything else!

Service Provider Lock

The Service provider (SP) lock is used to lock the cell phone to the
SP's SIM card. Once the cell phone is locked to a specific operator, if one
inserts a SIM card from a different operator the phone will refuse to accept it!
The cell phone will however accept another SIM card from the same operator.
