There is any apk that shows the system and hardware information about my Adroid phone??? I mean an aplication such as Everest (or msinfo32) does for Windows.
Try Android system Info.
You will me amazed how much information this application provides.
Elixir is one of the most widely downloaded comprehensive system info app for android.
Quick System Info is what I use (and was preinstalled in my LeeDroid ROM)
Quadrant also give me the same information that Android System Info.
