I've searched this issue in the forum and could not find any satisfy answers to the problem.
I've developed an app which was successfully tested and installed on the phone using unprotected UID and signed with my devcert.
Now I want to release it to Ovi store, so I did the final version by changing the app to use Nokia protected UID. Building and signing using my devcert was OK, but when I tried to install it on the phone I got this error "Unable to install a protected application from an untrusted application supplier".
This error did not happen to my other app which does not require any capability. The one that failed to install requires UserEnvironment capability.
Is this a known limitation of devcert? How do we ensure that our apps are OK before submitting them to Ovi store and request for Nokia express signing?
