 Now I'm trying to remember how I got ES Explorer to let me rename the 2 telephone related files to *.bak from *.apk.  I'm coming up with a blank as to how I did it.  I think I'm supposed to become a super user, but I've forgotten how.  Any help out there?

 Why not go to 2.2/Froyo?
To rename system files you need to root the gadget (zRoot); use RootExplorer to mount / as r+w, then long-touch each file to pull up the menu.
Renaming telephony.apk and phone.apk can extend battery life per what I've been reading.  I was hopeful that reverting these files to their original names would let me register my gadget with Google (ie, Android Market access!) but so far no joy.
