l've written a midlet that uses Location, Internet and PushRegistry function on the phone nokia 6110 Navigator. i self-signed the midlet then install without error on the nokia 6680, but i got error "Certificate error, contact the application supplier" when try install into nokia 6110 Navigator.
for your information, l'm using Netbean IDE for signing and the settings of th phone under Application Manager has set to allow Software Installation to "All" and Online Cert Checking to "Off".
from my research on internet, some people said nokia 60 3rd edition cannot install self-signed application but on another side, symbian http://www.symbiansigned.com/
provide certficate to sis developer for testing on the phone. why not java Midlet? or i've missed up anything?
