because the phone was more stable than thought, the carrier would be able to lop about two weeks off the expected launch time which would work out to about a March 15th release. At that is where things have stood until now, when a new report says that AT&T customers will have the first chance to grab the device. That would be followed by T-Mobile's launch with one for Verizon coming possibly as late as April with a BlackBerry Z10 model in an exclusive white color.
There has been a great debate over whether or not the phones are selling as well as originally thought. Amid reports that the Z10 was setting BlackBerry sales records in Canada and in the U.K., some analysts were saying that BlackBerry had stacked the deck by keeping inventories at retailers as low as 15 units in order to ensure a sell out. The U.S.launch should give a truer picture of what the real demand is for the BlackBerry Z10. The device should be followed a few weeks later with the launch of the BlackBerryQ10, the model that comes equipped with the famous BlackBerry QWERTY keyboard. Some buyers are waiting for the release of that model so that they can use the highly thought of BlackBerry physical keyboard.
