Apple's just posted up iPhone OS 3.1.2, which purports to fix some of iPhone OS 3.1's Greatest Bug Hits, including: Don't Wake (From Sleep), Lost Network Access, and everyone's all-time favorite, Video Stream Crash Dance. We're updating now, let us know how it goes for you in comments -- and there's an iPod touch update too, we're sure it's just as fun.
