I had hoped to "reply" with PMs to save "posting space," but here's what:
I deleted it. This is possible through TealMover (JackFlash would not move it to flash or delete it because it was "in use.") Once again, I didn't even have CHANCE to do soft reset, because it crashed on its own as I was selecting "mReset." The PIM Update file is marked "soft reset on install" for everyone's edification. You'll have to reset your system sound to "off" if that is how you had it before.
Then to make sure, I did hard reset and restored from the Card (did a "pre install backup" to be sure I was getting the "before picture." If you do this, be sure and delete the PIM update from your Hotsync folder or it will likely end up on the T3 again.
Since I don't sync with Outlook and have had no problems, it just seemed "messy" to me to leave a second file of same name in RAM (much like App Slip Rotate/Status Bar .prc's for the T3 Landscape can't be put in ROM 'cause the old ones are there . . . . GROAN. . . so you have two copies of THAT, too. Thanks to a rushed release and no apparent beta testing, the T3 and its "patches" is starting to look like a bullet-ridden barrel with bandaids.
I'll install this thing again later if need be, but again I haven't had problems and use the Palm Desktop - to-dos are deleting and I don't use Outlook. Thanks to all for the information - far more than PalmOne provided, by the way!
Cheers.
