I'm an developer, my company have a valid Publisher ID, so I can create developer certificates.
Recently I ran into strange issue - the app I'm developing, is signed with dev certificate, but is not installing on Sony Ericcson Vivaz, neither Satio.
System installer says "Certificate has expired". But for sure, this certificate IS NOT expired, because app could be installed on any Nokia device, without problems!
Few things I must note:
- date and time on devices is set correctly
- IMEIs are correct in Developer Cert Request
- App is not using Manufacturer Capabilities
- I set option "install everything" on device's settings
Maybe I need some special entries in PKG file?
Where is the problem...?
