Symbian 3rd Edition introduces mandatory signing for all installed SIS packages. For an application that uses no capabilities, or only capabilities that are open to all, it is possible to generate a new certificate and sign your SIS package with it. This process is recommended to be used with freeware applications.

Using a self-signed certificate means that the application is regarded as untrusted. Untrusted applications should use UIDs from the unprotected range of UIDs; otherwise the installation to a 3rd Edition device may fail.

Protected UID range:   0x00000000 … 0x7FFFFFFF
Unprotected UID range: 0x80000000 … 0xFFFFFFFF

Specifically, there are two important unprotected UID ranges:

UIDs for self-signed app. releases: 0xA0000000 … 0xAFFFFFFF
UIDs for test/development use:      0xE0000000 … 0xEFFFFFFF
