Last month we finally saw Android surpass the iPhone in terms of U.S. smartphone subscribers, and now Google's green robot has set its sights on RIM's comScore crown. At the end of December 2010, RIM held onto the top spot but saw a loss of 5.7 percent between September and December. Meanwhile, Android grew 7.3 percent during the same period of time, leaving it only 2.9 percent behind the BlackBerry manufacturer. In third place was Apple with 25 percent, and way back in fourth and fifth was Microsoft and Palm with 8.4 and 3.7 percent, respectively.
We've already seen Android beat out Symbian to become the top smartphone operating system in the world when it comes to number of devices shipped, and if it continues this crazy growth, it'll become the top OS in the U.S. by the next time we see comScore's numbers. The big question, though, is exactly how the Verizon iPhone will impact the numbers. It's hard to imagine Apple not seeing a huge growth, and if RIM continues its tumble, then we could see Apple slide into the No. 2 spot. RIM has some pretty exciting BlackBerrys on the horizon, though, and HP's big event is only a couple of days away, so things are definitely going to be heating up.
