I have a 6234 and on the memory card is some preinstalled apps/games inc. the bluetooth application 'presenter' by nokia. So I wanted to copy this across to a new 1GB memory card. With read only problems trying to copy it to my computer I then 'moved it' over to my phone's memory. Now I get a message "Certificate not on phone or sim". I have tried coping it back to the old memory card but still get the same message. How do I create a certificate for these. I don't care about the game demos but do want presenter application and now it doesn't work. Any suggestions?
