Last time we checked in with ComScore's report on smartphone platform market share among US subscribers three months ago, Android was doing a little happy dance as it overtook iOS for the number two spot overall. Well, the cuddly green bots have self-replicated yet again, enough to overtake RIM this time thanks in part to a 5.4 percent decline on BlackBerry's part (down to 30.4 percent in January) coupled with a 7.7 percent boost on the Android side, moving up to 31.2 percent. We imagine ComScore's next report -- covering the period through March -- will see a little boost on the iOS side thanks to Verizon's iPhone launch , but RIM's knight in shining armor might be further out; we still don't know when QNX -based phones are going to happen, after all, and devices like the Monaco don't really seem like cure-alls.
