I'm having the problem that a call to IAPClient::getUserAndDeviceId() always returns the status string "-1044: UserAndDeviceInfoFailed" and no data.
This happens on the Nokia PureView 808 with Symbian Belle FP 1 but does not happen on a Nokia C7 with Symbian Belle. Both phones have the latest updates applied.
I'm using the IAP framework in version 3.23.7. Also this no temporary problem, it happens since I got the device a couple of weeks ago.
