I have a problem with certificated applications update. If you could help me, I would be grateful to you...
I've an embedded middlet installed on a 3220 handset. The application was signed by an operator. I’ve tried to update it by installing the same application (a new version), but without signing, and I can’t (I see a mistake during the update).
Nevertheless, I’ve tried the opposite (to install an unsigned middlet, and then to update it with the signed middlet new version), and we haven’t had any problem.
¿Can we install (embedded or by OTA) a Midlet signed by any certificating company (manufacturer, operator or third), and then update it by installing the application, signed by another certificating company?
Thank you very much
