Overview

Backup and restore of applications using the backup_registration.xml file is not functioning as intended when the application is signed using a developer certificate.

Description

When the application is signed against either a trusted certificate or a self-signed certificate, backup and restore works as expected, provided that the backup registration file is included in the application SIS package.
When a developer certificate is used, the restore process fails for that application. This affects all certificates that are bound to specific device ID (IMEI) value(s), most notably developer certificates.

Solution

This has been fixed in S60 3rd Edition, FP1 in spring 2007 (e.g. Nokia N95, firmware 12.0.13 onwards).
