Query: Timing problem with certain palm devices

I have a Tungsten C. I had similar problems to the ones described by other reviewers. I did everything others have done (latest drivers, exchanged keyboard). I contacted Palm support and was told that some Palms have a "timing issue" with the keyboard and need to have a Rev B or Rev C sticker next to the serial number on the keyboard. I have not found a keyboard with a Rev B or Rev C sticker yet so I can't confirm that they will work.
