I am working on Nokia 6212. I have a SIM Card and the unlock midlet.
Unfortunately, I have the incorrect SSL server certificate when I am unlocking the secure element.
I have old keys. Maybe I can sign the midlet like you.
But I don't know how it works.
I have tried to use a software on windowz and sign the file.
Two new files are appeared into the jar file, It is the signature also.
But the Nokia Unlock Midlet, signed, can't be launched. I have a "invalid application" error.
Would you have some idea ?
