I backed up my file to SD card.
I edited the file as noted in the OP.
Soft Reset.
Messaging would open, but when I tapped a conversation or started a new one, it would just show me the messaging app with the OK button and the title bar at the top of the screen (but I could not see the top fields and the message area in the bottom).

I reverted back to my backup from SD and soft reset (which didn't work) so I deleted the file and soft reset and I'm back to normal.

Did anyone else have this issue?

EDIT: I did try the files that were uploaded here, but they yielded the same results as when I edited the file myself.
