SyncML on Palm Centro

[Atheist]

I've tried Synthesis SyncML Client Pro 3.0.2.27 DBG on Palm Centro with the following hosted free SyncML servers:
www.o-sync.com

http://sync.o-sync.com:80
Contacts, Events, Tasks, Notes

Failed with:
Error Code - 403

Google Sync

https://m.google.com:443/syncml
Contacts

Failed with:
Error Code - 500

www.everdroid.com

http://www.everdroid.com/sync/server
Contacts, Events, Tasks, Notes

Failed with:
Access denied (401)

wap4b.ru

http://wap4b.ru:80/sync
Contact, Events, Tasks, Notes

After checking either Contacts or Tasks and sending the portion of data the program switches into Waiting...
and failes on Receiving with:
Connection error (20003)

I could provide debug log (sysynclog_palm_session.pdb) if it was needed

QUESTIONS:

1. Is it known hosted free SyncML servers that work fine with Synthesis SyncML Client for Palm OS?
2. Could it be possible to use Google Sync with Synthesis SyncML Client for Palm OS?
