As reported by Endgadget:

At a 30,000-foot level, the global mobile phone sales numbers for the third quarter of 2010 just released by Gartner match up with what IDC posted a few days ago, but you might say the devil's in the details. These guys have all of the top five players -- Nokia, Samsung, LG, Apple, and RIM -- at noticeably lower total market shares than IDC did, suggesting that second-tier players like Sony Ericsson, Motorola, and HTC (if you can really call them "second-tier") are grabbing more hearts and minds. And hey, considering Motorola's prominent role at Verizon and HTC's ever-growing global presence, we could totally believe it. Notably, Nokia is well below 30 percent in Gartner's report at 28.2, a whopping drop of 8.5 percent year-over-year -- way more than the 4.1 percent drop that IDC's got pegged. Of course, there's no way of knowing which of the two reports is more accurate -- and you know how margins of error work with these things. Hey, at least the rankings are the same, right?

Update: As commenters have pointed out, the Gartner report also puts Android at 25.5 percent market share, moving past BlackBerry OS to become the number two smartphone platform behind Symbian (they've got iOS at third, BlackBerry fourth). Considering the platform's trajectory this year and sheer variety of Android phones now being solid worldwide, it's no surprise.
And also from Endgadget (h/t BoomBustBlogger Indy):
Nielsen's just released a report finding that 29.7 percent of mobile users in the United States now own a smartphone. Of that 29.7 percent (which you can see in the pie chart above), 27.9 percent of them have iPhones, 27.4 percent are BlackBerry users, and 22.7 percent have an Android device. Windows Mobile, Symbian, Linux and Palm are left to divide up the remaining chunk -- about 22 percent -- of the market. That's a massive shift from the beginning of the year, when the iPhone boasted 28 percent of the market, BlackBerry had 35 percent, and Windows Mobile about 19 percent. The biggest winner in this story is Android, which has gone from 9 percent of the smartphone-owning market at the beginning of the year, to 22.7 percent of the market today. The story looks a bit different, however, when people are asked about what kind of smartphone they would like to own next. In that case, Apple and Google are the big winners, with 30 percent of 'likely' smartphone upgraders' reporting they'd like an iPhone, while 28 percent said they want an Android device, and only 13 percent reporting that they're interested in a BlackBerry device.
