this this and it didn't work. Strange because it's easy and straight forward.
followed this to the tee. No email widget. checked the file and the icon changed. I tried to install and it said failed.
Decided maybe I'll just stick with the icon and the other secemail.apk files are gone. I did not delete them, I just renamed them and took the "k" and "x" off of the files (respectively)..
only potential thing I didn't get was "switch over to read write mode. did you mean edit the file and change its properties for use to read/write ? (which it is my default)
