a) i remember when you were saying that the bb10 only sold 300,000 z10's
b) I also remember when blackberry was selling about 12 million phones per quarter- that was when the stock was betwen $70-140/ share. Its currently at $13
c) This 1 million phone number is for one phone for one month of the quarter. If you put that into context then it goes like, 3 months x 1 million z10's+ 6.7 million bb7 phones = 9.7 million phones.
d) that 1 million phones excludes the majority of its markets(like the United States, Brazil, China, etc.) for the month, and its a low estimate. If you increase that number to 2 million phones which are more then likely selling at a 30% margin you come out with (3 monthsx2millionx($600*30%)=1.2 billion gross margin and this number is only for the z10.
Good luck to you.
