I didn't trust the relevance of anything as old as 2006. I used the information in http://supportforums.blackberry.com/...STEM/m-p/92398
as my guide for removing potentially offending cod files.
Anyone have a copy of the official TMO 220.127.116.110 Handheld OS?
I've cleared the old software and put 18.104.22.1684 on, then added the data back from the most recent backup. Guided by RIM support, I didn't load "timezoneotapatcher" or ICQ.
I'm having trouble getting a UMA connection with 544, but that's the subject of another thread.
