BlackBerry announced today that its new Z10 handset will debut tomorrow and roll out worldwide over the next few months. The Z10 will land in the UK starting tomorrow, with a launch in Canada shortly afterwards on February 5th. The US will finally get the handset in March. In the US, it will be available from AT&T, Verizon, and T-Mobile. Sprint is apparently carrying only the qwerty Q10 sometime this year. Pricing and exact launch details for the Z10 will vary according to carrier with pre-orders starting soon.
