I presume your device is developer unlocked as you can not normally see the register on a standard WP7 device.
If you have a Mozart you can download the HTC Connection setup app which is free, it should have all the settings you need otherwise O2 should be able to supply you the required settings.
Thanks, but not realy what I search. I have not a o2 SIM-Card, this dont interest me.
I will tray to force with the "ZUNE" the new update for the Mozart o2 UK v1.41 and need for this the correct MobileOperator value.
Again, I need from /HKEY_LOCAL_MACHINE/System/Platform/DeviceTargetingInfo/MobileOperator the correct value for a o2 UK phone (device).
