re: exit button
why not put it back and "trap" it and ask the user if he really wants to exit?
re: installation
it gives me error saying the prog may be not done for this phone blah blah blah
didn't try with pcsuite, but probably (?) it stops such apps from being installed, while "manual" install from phone just warns you
could you try to recompile it adding that "series 60 ID" or whatever it was?
