BlackBerry CEO Thorsten Heins cheered investors telling an interviewer that the new Z10 smartphone has performed better than expected. "[I]t's also been attractive for customers coming from other platforms. We are a little surprised by that," he told a Spanish newspaper. The Z10 is expected to reach 21 countries by the end of this week, although U.S. carriers have not set a firm launch date. Verizon Wireless has indicated a late March debut, while T-Mobile USA has pointed to a mid-March ship.
