Ok, so I've spent the last 6 months using 2.2 Froyo and I love it, however, I was using a leaked build on a rooted system. Today, I decided to unroot and move back down to official 2.1 so I could do an official upgrade to 2.2. However my Droid tells me that my system software is up to date. Since I was rooted before and wasn't notified of any rolling updates, did I miss something? I assumed I would be able to OTA to 2.2 once I was back on an official Google build.
