The Boy Genius Report, back on November 9th (10 days ago,) reported that
RIM was aware of the problem and was investigating it. 10 days later, it's STILL going on. For WEEKS now, the typical time for a message to be confirmed as delivered has been 5-6 minutes, for both myself & my fiancée. And it shows no signs of improving.
So nice to know that RIM has assigned a crack team of their best experts to the task of correcting this ASAP. *rolling eyes sarcastically*
