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.
