Hidden menus in Android phone
I noticed some hidden menus in the Android Dev Phone 1 (ADP1). By entering following code sequence *#*#4636#*#* (*#*#info#*#*) in the Dialer application, you get access to Phone and Battery information menus, with some "extra" information. In the Phone information menu there is also a place at the very bottom of the menu to add your own carrier SMSC number, so that you can send text (sms) messages. Access to the the other "hidden menu" is by entering following code sequence *#*#7262626#*#* (*#*#ramanam#*#*) in the Dialer application. It is actually a built-in FieldTest application that gives a lot of information about the mobile networks (both 2G and 3G). Since the "FieldTest menu" is actually an application, you can download the application AnyCut and use it to add a shortcut to the FieldTest application "on the screen". Several other phones also have similar "FieldTest menus", for example in iPhone and some Nokias it is *3001#12345#*. There are also some free applications for different phones that show carrier information, such as for example PyNetMony, NetMonitor and CellTrack. For Android there is at least one free application for this called CellFinder that also use the built-in gps when trying to show basestations on the integrated google map.
