Google Calendar service is now available from your Web-capable mobile phone. Users can see appoints complete with date, time, location and description. One can not change or delete existing appointments, but can add new ones and check previous and forthcoming events.
But the option to change or delete existing appointments is missing. There is also an additional link to Google Maps. U.S. Google Calendar subscribers can be reminded of events via SMS.
The service is free of charge, though it needs internet access, which is not free.
