I'm missing the beginning of the conversation. So I can only mention 
that syncml-http-server works only with the newest SVN stuff. Port 8080 
definitely works - except that you run another service on this port.

Ports until port 80 are restricted because they were officially 
associated with services and the idea was and is that only authorized 
persons (usually called administrators known as root) should be able to 
start such services. Therefore normal users without root privileges can 
  only establish servers with port numbers higher than port 1024.

You open web connections as a client. If you start a sniffer like 
wireshark then you can see that the server use port 80 and you use a 
port over 1024. This is basic TCP/IP. If you start syncml-http-server 
then you starts a server and not a client and this is a completely 
different thing.

... I don't understand this ... :(

Please describe clearly what you configured. Example:

1. member: 1
    plugin: syncml-http-server
    params: port 8080

2. member: 2
    plugin: syncml-http-client
    params: url http://my.provider.de/funambol/ds

Again please note, that the whole SyncML over HTTP stuff only works in 
newest SVN releases. Compatibility with some servers is tested and 
phones with SyncML over HTTP clients are rare (except of UIQ).

Best regards

Michael
