I apologise if the answer to this question is obvious, or if the question has been asked before. I am a developer of mobile games, and when installing to Series 60 devices a message appears concerning the "Untrusted" application.
My question is, what is the cheapest, quickest way to have your JAR signed by a certificate that is acceptable to every Series 60 device and would stop this message appearing.
It should be noted that the game uses JSR-120 Wireless Messaging API.
Thanks for any help.
