Last night my original Droid that I use at night top stream radio over WiFi got an upgrade to 2.2.3. I haven't heard about that coming. Now if my Bionic will get the bug fix and ICS I will be a happy camper.
I got the same thing around 1AM EST. I noticed the update only mentioned that it contained several important security updates. It was less than 1MB too. Guess it's nothing to concerning.
Anywho, I've had this OG Droid since release day and can't wait to get rid of it! It's a dinosaur.
