I don't understand
taken of Symbian_Signed_Criteria.
5. Check whether the package is an update to the C32 (i.e. the UID is specified as the Symbianowned 0x101f7989). If so, the package should contain an .ESK file and an explanation should be provided for the purpose of this with the application.
I don't know what's mean "update C32" ni with this example. "What is a package update to the C32"??
Also i don't know what is a .ESK file, any idea?
