I have a "no service" problem
I bought iPhone at U.S and using it in Australia.
It was all fine around 2weeks.
But suddenly the signal bar was getting down.
At last it shows "no service ".
Sometimes 5 bars and "no service"...
It is repetition.
I do not have any problem , Other than it.
I read following thread.
Restore for 1.1.1.
Upgrade to 1.1.2 and restore 1.1.1.
Downgrade modem base band for 1.1.1.
There is no improvement...
Would anybody help me?
iPhone : OTB1.1.1
iPhone SW : 1.1.1
Carrier : OPTUS in Australia
Serial : 7v7418jxxxx
OS : WinXP SP2
iTunes : 7.5
