If Optus is your carrier and you're waiting for the BlackBerry Q10 to arrive, it's looking like you might not have to wait all that much longer. Looking around on the Optus website as well as their Facebook page, it would appear as though Optus has no idea when the device in coming but an email sent out to their business customers tells a different story.
June 24th is what was noted in the email so unless that email sent out was a mistake that is when Optus business customers should be able to get their hands on one. Consumer availability shouldn't be that far behind it. Sadly, no pricing was noted in the mail so we'll have to wait and see.
