Phone.app codes

Like many other GSM phones, iPhone supports special codes that can be entered via keypad.

*#06#                         - everyone knows that it displays IMEI, but it's here for completeness
*3001#12345#*[call]           - start Field Test app (network monitor)
*#30X#[call], 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.
