I would like to kwnow in which situations the 6600 come up with an Authorisation Failed message in instalation time. I really do not understand when it appears. A list of root causes will be very very helpfull
I would like to know how you are transfering the .Jar file.Through IR or BT ??
Also this might happen when something is wrong with your JAD/MF file.
a) Certificate is invalid or outdated (if your midlet is signed)
b) MIDlet-Permissions contains permissions that this phone doesn't support
c) something else
