Last week CEO Thorsten Heins ranted and raved about how amazingly well the BlackBerry Z10 did in Canada and the U.K. “In the UK, we have seen close to three times our best performance ever for the first week of sales for a BlackBerry smartphone,” Heins said. According to Deutsche Bank‘s Brian Modoff, Heins may be looking through rose colored glasses. After conducting a survey of 60 stores carrying BlackBerry, Modoff found a slightly different reality. “In Canada, many stores reported being sold out of the Z10 and the sales force was well-versed on the device’s attributes; however, a few representatives told us that they did not receive a large initial inventory. In the U.K., the sales force was better-versed on the feature sets relative to the week prior; however, no stores were sold out,” Modoff told AllThingsD. [Source: AllThingsD]
