Sorry if this has been posted and answered before, my searching has turned up very little.

We have network edition and soon will have a lot of blackberry users who will need to sync email and calendar.

We do not have blackberry enterprise server and do not want it.

With budgets being tight we do not want to spend any extra supporting these blackberry users.

Is there any java client I can install on the blackberry which will sync for free?

Thanks for any help
