Motorola Milestone owners, your moment is now. The Android 2.1 update you've been waiting for is now available en masse. Users outside of Hong Kong (which already got served) have received notice that an over-the-air update is available to unlock the nine home-screens, Google Earth, and other goodness that comes along with the latest flavor of Google's mobile OS. When can US-bound Verizon subscribers hope to get their point release of goodness? That, sadly, is still TBD, but we're guessing it'll be any day now.
