Hidden Menus is a simple application that lists some hidden components like "checkin" (*#*#2432546#*#*) and "info" (*#*#4636#*#*), extremely useful for any upcoming OTA!
Feel free to suggest other devices shortcuts.
For any bug or "force close" it is better a full bug report in this xda thread http://goo.gl/YJ9sI rather than a useless negative comment here.
WARNING: some entry might not work depending on the device/rom.
