BlackBerry launched its much-awaited Z10 smartphone in March, holding out the promise the company might stem its long slide in market share against Apple's iPhone and Android-based smartphones.
Some observers guess that BlackBerry is shipping upwards of 1 million Z10 and entry-level Q10 smartphones per month. But on June 28, the company reported disappointing sales and earnings numbers, and executives didn't disclose sales data for its "BB10" devices.
