Yes you can. There are a couple of way you can use a Blackberry with Zimbra. If you are wanting to use the full functionally of the BB meaning email and calendar you will need to purchase the network edition and also purchase a Blackberry Enterprise Server.
If you just need email then you can use the open source version which is free and just enter your server settings in to your BB. It won't be a push but your BB will get your email for you.
On a side note, if you don't need your calendar updated as often there is a way to sync your calendar to your BB with the open source version but it's a long drawn out process involving google. The calendar won't update but what appears to me about once a day sometime over night.
