phone (task, battery, ...) information.

There are three secret codes. One for turn Service menu ON, one for more detailed version info and one for
exitcode information (what task and why reset or power off the phone).

James Bond feature
There are one another service feature: display last not-normal exitcode.
1. You need to create phonebook entry like DEBUG (with IMSI), but name it JamesBond.
2. Now You can view last exitcode on main screen with wallpaper (see screenshot).
3. If You don't see anything, try this: Restart the phone to the PIN-Entry screen and wait, until
it automatically power-off. Now You can see something like on my screenshot.
