The first step's you need to get your certificate for your IMEI.
I recomended http://cer.s603rd.cn. You can download your certificate within 12 hours dan the signsys software. Just chek again on the web
The second steps's you have to install signsys on your phone and put the certificate on your phone.
By using the signsys dan the certificate you can make sign version of your symbian software.
