BlackBerry 10 is now being tested by over 50 carriers, Research In Motion (RIMM +4.7%) CEO Thorsten Heins disclosed in an e-mailed statement. That puts RIM on track to launch BB10 devices in early Q1 - Jefferies claimed earlier this month the first devices won't arrive until March. Either way, the OS faces an uphill battle in light of Android and iOS' hegemony in developed markets, and it will get tougher if Windows Phone 8 fares well this holiday season.
