Basically any symbian platform phone will have to sign their .sis format application before it can be install on your phone.
This signing process is to bind the application with your phone IMEI through a certificate.
and only signed applications are identified as trusted and will be allow to install by the symbian OS.
This is to protect your phone from unwanted/untrusted application which might automatically install in the background of your OS like Virus/Trojan.
However, all applications release/develop by Nokia are in the exception of signing, because the OS will automatic identified the application as trusted.
Only symbian platform software developers have the abilities to provide you your phone certificate which is needed for the signing process.
this certificate embedded your phone IMEI.
you can get your cert here
http://andy.ehandysoft.com/devcert.phpThe main purpose of h@cking is to enable you to install application into your phone without signing with your cert.
because some cr@cked application although it is signed with your cert, it is still will be indentified as an untrusted application.
so to be able to use the C@*# application most user will h@ck their phone to by pass signing process.
