How do you download Gmail calendars onto a blackberry?

google offer quite an array of there products in a mobile format. I would suggest the easiest way to have gMail Calenders on you handset would be to visit 'mobile.google.com' for US/Canada and 'mobile.google.co.uk' for the United Kingdom, do this using your Blackberry Browser.

You should be presented with a link to download the 'google Updater' application for Blackberry and with this you simply install the packages you would like to use and enter your google Account details.

With google Calenders you also get the ability to Syncronise with your Blackberry calender but unfortunatly at this moment in time only information can be retrieved FROM google and not placed to.
