Expired Certificate Error in Nokia s60 or Nokia 5233
Expired Certificateis a error because the application that we installed in our Nokia N-series has expired, this error is not because the application is unsigned. To solve Expired Certificate you should not to change the date on your mobile, there is a better solution:Sign4ever. The application which one you want to sign in the same folder of Sign4ever in your PC and execute the Sign4ever. Then press any key to continue and follow the instruction of blue screen. Then signed.sis will appear with 2-3 application. Install the application signed.sis and the error of expired certificate is not a problem forever.
