UPDATE: According to Droid Life, the update should start tonight, but it may just be a "soak test", for users that signed up via Motorola's support forums. That's not entirely confirmed at this point, so if you happen to get the update, drop us a line.
A couple of notes from Motorola about the update:
- The update will be pushed late tonight. If you go to bed, it should be waiting for you in the morning.
