If you’re among those who have been blown away by the redesigned BlackBerry 10 experience, March 15th is going to be a special day for you. BlackBerry’s flagship smartphone, the Z10, is all set to launch in the U.S. markets on AT&T on this day. So yes, you no longer have to wait until March 27th like we’d all first thought.

Even though T-Mobile was among the first to make the announcement, looks like AT&T has beat it in this race and will officially be the first carrier in the U.S. to launch the Z10. We can also expect T-Mobile and Verizon to follow suit, but you’ll just have to wait a little longer for them to bring out the phone.

Of course, just how well the phone is doing in the markets is a big point of contention. While some reports are saying that the phone’s flying off the racks in Canada and the U.K., skeptics feel it could be because of lower supply rather than the popularity of the device. The Q10 smartphone with its QWERTY keypad will also launch within a few weeks of the Z10’s launch, so if you want to remain a BlackBerry purist, you’ll just have to wait for a little longer.
