Syncing Google Calendar with Phone Mobile (various approach)

I just purchase a cheap multimedia phone Nokia 3110 classic. Since this Mobile support GPRS/EDGE and have built-in Calendar & SyncML (are there still any phone without this functionality). I'm interest in synching its calendar with my Google Calendar. Somehow I have multiple calendar which I want to sync with my mobile phone Calendar, so the solution must be able to sync multiple calendar with my phone. There's somehow many solutions

1. Syncing Google Calendar with Outlook Calendar and sync again with Nokia PC Suite - I can't do this since I'm not using Outlook anymore.
2. Gcalsync - This seems to be the best solution. Somehow it's not 100% working for me. Gcalsync refuse to connect to my Calendar (invalid ports). And I can't set my phone proxy as said in Gcalsync web-site. Anyways I can sync the calendar if I specified my full private URL, thus means I can only sync 1 calendar.
   
3. Scheduleworld - A free services, using Open-Source sync server funambol & SyncML, which you can store your mobile phone contacts, calendar, and notes on server. Scheduleworld can also sync with Google Calendar, although only one calendar at a time (but you can specify any Calendar). This works for me. But again, one calendar.
4. Goosync - A (partially) free services to sync Google Calendar with Mobile phone Calendar using SyncML. This seems to be my perfect solution. Somehow syncing multiple calendar is not free. Free service only allow you to sync your default Calendar. I don't sure if this works because I didn't try it out, but looks very promising.
5. WAP page of Google Calendar - Google actually have a WAP page to access Calendar on Mobile phone. Anyways think of the cost that I need to pay to access it every time. Anyways I can use this to add my event & appointment.
   

Anyways I found my solution. I setup Gcalsync to sync my personal Calendar, while setting Scheduleworld to sync my work Calendar. This updates my phone Calendar with both Google Calendars that I want. I'll wait until Gcalsync work totally for me and switch back to 100% Gcalsync. For now this is just works.
