My sony CLIE PEG-SJ20 is not compatible with Vista. Is there some mechanism I can install that will make it work with Vista?

I had the same problem with my clie peg-sj20 on my vista home basic based laptop. I could not hotsync after installing the original software. I've never tried to use my pda with this setup before so I was trying to find a way to make it work when I found this post, figured I would reply with what I found.
My Sony clie peg-sj20 runs the Palm o.s. 4.1 software and apparently Sony no longer supports this model. So after trying to hotsync and letting the Windows vista install wizard find the proper software, it suggested contacting the manufacturer of the operating system. I went to the Palm websight and downloaded the Palm o.s. 6.2 software which is compatible with vista, even though it doesn't say it supports the sj20. After installing it I performed a hotsync during setup when I was prompted to do so, and it totally worked. I'm not sure if this version works with other applications but it enabled me to hotsync running vista.
Hope this helps someone out there. Good luck.

I posted this same question to Sony online support. Answer from Sony is that support ended in 2004 and Vista will not be supported on the SJ20. The recommended trying 3rd party Palm OS management tools. I tried 2 based on a web search and both had issues with Vista and my SJ20. One I got to work and back up all my contacts, but each time I connect if eventually creates an error during the sync process and freezes the Sony SJ20. Good luck. I'm maintaining XP systems in my home to combat to poor Vista world.
