As of this writing, it looks like Motorola is on the fence regarding a future update to Android 2.2, as it relates to the Milestone. It just got Android 2.1, so we can see where Motorola is coming from. That's from a logic standpoint. But, from the much healthier standpoint of wanting the most current software on our device at all times, we're wondering what they're thinking. Thankfully, though, we've got a great development community out there -- and here you have Android 2.2, in build FRF91 -- which has already made the rounds over plenty of devices already.
Of course, we all know that the Milestone is locked down. It uses the same eFuse technology that became so shockingly famous over the release of the Droid X the last couple of weeks. But, that's not stopping the 7 months of hard work since its release. There's something to do with "second boots" that we're honestly going to say we're not sure the details of, but it works, and Froyo is definitely running on a Motorola Milestone. So, that's just plain good news. Check out the video below to see for yourself, and we'll keep you informed of any future changes, as well.
