Are you speaking from experience on this issue?
Yes.
I have not yet been able to get Yahoo's Intellisync to recognize the Zaurus "conduit." It will only accept data syncing from Outlook, Lotus, ACT, Palm or Pocket PC. Unless there is some way to trick it to see the SL conduit, I don't see how this is possible. Could you please elaborate? I would really appreciate knowing how to do this. So far I'm double entering everything in Yahoo and Zaurus, which is really getting ridiculous.
I use to sync my Zaurus to Yahoo! all of the time, using Sharp's Intellisync that came with the SL-5500 (2.x ROM) and Yahoo! Intellisync (I'm currently using Version 1.0.1.12). As I said, it was a matter of installing the Zaurus Intellisync first, then Yahoo!.
Run Intellisync for Yahoo!, and click on "Setup". Click "Application Settings". Then for each of the Applications, click on "Choose" and select "Zaurus" from the "Available Translators". Also, I use USB/TCP-IP rather than USB/I-O, but that really shouldn't have any impact on Intellisync's ability to find the Zaurus conduit.
I haven't actually tested it with the new Sharp Intellisync for the 3.0 ROM. However, I believe that Sharp only modified the backend (Zaurus) side of things for their proprietary DTM support, so it
should still work with Yahoo!'s Intellisync. The Zaurus 3.0 does still show up in Yahoo!'s Intellisync.
It's also possible that newer versions of Yahoo! might not see the Zaurus, but, then again, I believe that the method that Intellisync employs to discover which conduits are available is standardized.
