re: BlackBerry Comeback: RIM Must Win Developer Support
This isn't true at all. In the US iOS has risen to 51% marketshare, and that's still without T-Mobile, which will be selling the iPhone in three months or so.
Worldwide, it's now up to 25.1% according to one company. This is despite it not being on China Mobile, by far the largest cell carrier, with over 700 million customers, or the largest carrier in Japan (though 2/3rds of the smartphones sold there were iPhones).
There should be little doubt that if Apple does come out with a less expensive phone, as its now being rumored, their sales will grow appreciably.
Also, much of that Android phone growth is attributed to Samsung. But they have not given quarterly sales, or shipment info since the first quarter of 2011, so all of the numbers we see are just guesses, with no hope of verification. That has to be kept in mind.
