*#06#                     - everyone knows that it displays IMEI, but it's here for completeness
*3001#12345#*           - start Field Test app (network monitor)
*#30X#, where X=1..9    - generate fake incoming call; the phone will become kind of messed up, thinking that it's on a call until you restart. Can be used to stream music to Bluetooth headset.
