I notice that there are some freeware applications for Symbian OS 9.1 that are now distributed as unsigned SIS files. For example:

  • ActiveFile - a free file manager for S60 3rd Edition.
  • GNUBox - an application that allows you to use PC’s Internet connection from your phone.
  • TaskSpy - a task manager for S60 3rd Edition.
  • Screenshot - a screenshot capturing application (this application is developed by me).

Symbian SignedWhy do the developers release unsigned applications? I think the biggest reason is because Symbian Signed Authority normally needs a couple of weeks (and sometimes months) to sign an application. Although they said on their web site that signing for freeware applications should take 2 - 3 weeks, this will not happen in most of the cases. It had made frustration to many of freeware developers.

How do the users install unsigned applications then? There are some people who have provided step-by-step instructions how to sign them ourselves. Basically, a user who wants to sign an unsigned application has to register with Symbian Signed and then download a certificate/key pair for his/her phone.

If everyone can sign any applications using their own certificates, why do we need Symbian Signed at the first place? What is the point of having signing if the users can sign applications themselves? It just creates extra steps for the users and makes developers’ life more difficult.
