I am so desperate about getting a solution for our head eating problem.
The problem is that our J2ME application (MIDP2.0) is signed by Verisign and we have all the items related to the certificate in place.
We tested the application on several phones...working fine.
But on Nokia 5310 (S40 5th edition), when i try to download the application and install it, it throws an error "No Valid Certificate". But the application is signed by Verisign.
WE contacted Verisign people regarding this issue but they did not have any such info related to 5310..they were telling, the signed app should work on all devices..
