We all know that a lot is riding on the success of BlackBerry 10 for the Canadian-based handset maker. Most would agree that it's sink or swim at this point. The life preservers have been tossed out in the form of the BlackBerry Z10 and early indications from a few key markets show the rebranded company still has plenty of fight left.

BlackBerry posted an official statement on their website earlier today outlining some initial sales figures for the latest handset. President and CEO Thorsten Heins said yesterday was the best day ever for the first day launch of a new BlackBerry smartphone in Canada. He didn't give exact sales figures but he did say it was more than 50 percent better than any other BlackBerry launch in Canada's history. Considering local loyalty over the years, that's a pretty telling statement.

Furthermore, the executive pointed out that sales of the new BlackBerry handset in the UK are close to three times better than the previous best first week of sales. It certainly seems like BlackBerry is off to a good start, but will those sales records be replicated in other markets, namely in the US?

That remains to be seen as Android, iOS and Windows Phone have pretty much the entire US market locked up. Early reviews of the Z10 show promise but there are still some holes that the company needs to patch in the proverbial ship to keep it sailing ahead for the foreseeable future.
