Obviously it's no consolation to E71 or E66 owners, which lost BlackBerry Connect back in July, but if you're still battling on with the E90 Communicator you can safely top up your firmware and still stay in touch with your BlackBerry email.
Originally there was a little confusion as to whether an updated client would be available for the new v300 firmware, but thankfully that's all been cleared up now.
Simply hop on over to Nokia's Business Software Downloads page and tap in your details. You should then find an updated v4 BlackBerry Connect client to drag down and stick on your handset. Crisis averted.
