Works from the dialer:
##634# - Shows color variant and lifetime counter.
Needs native toast launcher:
##778# - Opens service tools, but nothing seems to be doable there. It says "select function set" but there's nothing to select.
##3282# - Opens field test. Tried locking network to 3G on one of the networks here that have bad reception, and that works perfectly.
##777# or ##777w/call - User Content Reset
##7820# or ##7820w/call - SIM Lock Status
##634# - Shows color variant and lifetime counter.
