The focus is on support for Gmail, but the search giant has promised synchronisation support for Calendar and Contacts.
"It allows users to access Gmail, Google Calendar and Contacts using the built-in BlackBerry smartphone applications they already know and love," wrote Raju Gulabani, product management director at Google, on the company's official enterprise blog.
"For instance, users can instantly receive Gmail messages within the built-in email client on their BlackBerry smartphones. And they can continue to use the same shortcuts to manage their BlackBerry messages."
Existing BlackBerry applications already support Google's various services, but this new component promises tighter integration with the device. Gmail emails are pushed to the BlackBerry within one minute, according to Google, and emails marked as read or deleted on the BlackBerry are reflected in Gmail and vice versa.
However, calendar integration is currently only one way, so additions and changes made to Google Calendar are reflected on the BlackBerry, but not the other way round.
Google Apps Connector for BlackBerry Enterprise Server is now in closed beta testing with a selection of companies and universities, and is set to become freely available to all Premier and Education Edition customers in July.
