Just was going through my hard drive, and found a text file with a list of codes for some special menus etc.. Just thought I would do a dump here (mind out of the gutter!) in case its any use to anyone who is still using a mobile phone from the techno-ice age days.

##786# is your stats (call time, number of calls, etc)
##3282# is 3g data programming, most of this stuff you need your MSL code to get into.
##MSL# brings you to the MDN/MSID provisioning menu.
