I had a Z10 that I got at launch, it wouldn't let me send attachments or reply to emails from my imap account, search for "BB10 smtp bug" making it unusable for me and others(not to mention the 30 day of emails limit problem). Every day people were complaining on BB's Facebook page about their emails and BB simply ignored all if them, including me.
Shortly after it got the Q10 it started showing the same problems, I even started a thread about it(look it up), it was the leak that fixed it. And later the leak wiped 3 months of emails and all my texts.
