The fine folks at Google recently announced:
You can now access your Google Calendar account from your mobile phone! Just visit mobile.google.com/calendar/ with your phone’s web browser and once you’re logged in, you’ll see your list of upcoming events with date and time information in an easy-to-browse format.
This is great!
However, what’d I’d really appreciate for my BlackBerry is a J2ME version of Google Calendar.
Since Google already delivers a J2ME version of GMail for my BlackBerry, I hope that the J2ME version of Google Calendar isn’t too far away …

Yes I want this as well, J2ME Google Calendar would be great. I used gcalsync to sync my events to my phone but it doesnt seem to sync all my events.
you might want to check out Snaptu — it’s a j2me app that contains Google Calendar among other goodies.
sorry, forgot the link: http://www.snaptu.com/a/gcalendar
