iPhone 3G keeps defaulting to time zone Cupertino

[markfraser]

I noticed my mail is showing the wrong 'received' time. On receiving a mail, it shows the received time several hours before the current time on my phone. The time on my phone is correct.

So I looked in the time zone settings and it is set to Cupertino. I have repeatedly set this to London or Edinburgh but when I go to mail, the times are still wrong. When I return to Prefs, the time zone has reset to Cupertino. I have tested all this loads of times and my changes seem to stick until I go to Mail. As soon as I do this, it revert to Cupertino. This happens regardless of the Time Zone Support settings in mail.

I searched the forum and can't find anything on this so I must be missing something very obvious - but what?

I reset my iPhone last week after it locked up answering an incoming call while I was composing an SMS. The phone locked and the screen went dead. I tried switching off, but no response. I plugged it into my mac to see if it was still alive and it came up in itunes, ready t sync as if there was no problem at all. But I could not access the phone from it's screen. I read about the reset in the Apple online iPhone Troubleshooting Assistant and performed the reset holding the Home and Sleep/Wake buttons for 10 seconds.
Since then I have been stuck in Cupertino. Resetting the Time Zone to Melbourne Australia, works, but as soon as I leave the settings app my Time Zone resets to Cupertino. I have upgraded the software to 2.0.1 expecting a bug fix, but no luck there.
Tried submitting a fault with Apple but could not find a TAC for iPhone OS, only hardware. Any ideas?

After the visit to the genius bar all, they reset the phone from iTunes and changed the location back to London. Got home then restored the phone from backup and all has been well.

it seems that this fault is happen after reseting the phone from the handset.
:D
