I updated my firmware to 071.004.
When I first rebooted the phone after the update, some weird processes started (for example: SecureWidgetInstaller, SecureWidgetPreInstaller, ShareCommServer).
As soon as one of these processes start, the phone automatically establishes data connection and starts transferring data.
As this data connection cannot be shut down by no means, the phone is useless at the moment.
I kindly ask for any help.
