I am seeing too many post regarding symbian signing process.

1) I also got the information that any symbian application developer organization has to purchase PublisherId from Trust center with cost of $200 which is valid for 1 year but what after 1 year??

2) Again publisherId is not enough to sign symbian application but now needed to have developerId but what cost I need to pay for the same???

3) After this process I can send my application to symbian foundation to sign my application. Will I have to pay here again for subsequent signing??

There is too much detail on symbian developer site but not very focused information regarding the exact process, methods and cost detail available anywhere.

Can any body tell me where can I find very clear idea regarding signing of application?

Can any body tell me what are the different methods of signing?

please provide correct location and information to find all these stuff.
