I Successfully made visible the Dev Mode Icon found here
"/usr/palm/applications/com.palm.app.devmodeswitcher/appinfo.json" by changing the line that says "visible": false to visible:true

I tried to edit this same file again back to "Visible": false so I could use the new app "DevMode Launcher v0.2.0 [was 0.1.1](7/19)" instead

However I was not able to change (or even see it) it back.

When I entered the edit mode by typing "vi /usr/palm/applications/com.palm.app.devmodeswitcher/appinfo.json" all I got was a list of "~"s

Any ideas ?

Thanks ChasPalm
