Hidden Menus

[tcat]

Is there a way to access Hidden Menus like you can on a phone? Like dialing *#0*# or some such string. I see an app called "Dialer" in Manage Applications, but nothing in the app drawer to access a dialer to try anything. I had come across this about calibrating the compass and wanted to try it: http://forum.xda-developers.com/show...9&postcount=16

I wonder if the SGP needs to be rooted to access anything like this?
