Sony Ericsson's Android-based XPERIA X10 was mighty sluggish when we played with it at the launch a couple weeks ago, but this new video from hdblog.it shows what looks like a much newer software build that's dramatically faster and more responsive. There's nothing much new here in terms of features, but just the fact that the X10 is in the wild and running well is encouraging -- especially since we're really digging that media playback interface. Now all we need is some Stateside shipping details and we'll be all set. Video after the break.
