i am a flash developer but am totally new to symbian packaging. i use the nokia online flash lite packager to create a symbian package for my flash lite application, but when i create an sis file (unsigned) it give certificate error when installing on nokia symbian phones (3rd n 5th edition).
is an sisx file compulsory to run on 3rd n 5 th edition nokia symbians?
is signing sis files compulsory?
is a unique uid compulsory for sis files?
if not then what may be the problem?
thanks in advance.
