Before I do the yahoo trick, though, I'd IMMEDIATELY download and run
http://www.dotfred.net/ on your PPC.
Set the backup location to your SD card, back up, and then transfer the file to your computer. I do a backup once every month and store it on my comp JUST IN CASE.
And running that Yahoo2Go thing sounds pretty cool!
Also, dashwire will do an OTA contact backup, meaning as soon as you connect, it will store your contacts ONLINE on your account.
I'm glad it all worked out for ya! Just don't let it sun bathe again
