help plzzzzzzzzzzzz crete file cer key
you need to have publicer-ID for it.
If you don't have one, you need to use Open signed Off-Line
If u have publisher id then only u can create it for your phone otherwise u have to use the opensigning facility which is present in symbiansigned.com.
Lets ignore more posts on this thread.
And the answer is, go to www.Symbiansigned.com, and read the instructions from the page.
And please do not make more accounts to ask this question again. I suppose this is second account you are asking this question already.
