Ok, I got the download a little after 2:00am EST. My guess is that the download was avail for a limited number and was designed to go out to the Moto Test group but only because they were informed of it. Had they kept it to themselves, they probably would have gotten it but as I (we) were continuously checking, we got in first.
So far-
Positives: Seems to be smoother overal. The major bugs seem to be fixed i.e. Text in order, music player fine, battery info not FC. I like the new dialer app and I haven't seen the VCast store on the phone, not sure if it was left out.
Negatives: Right when I loaded up I got a black screen with the notification bar. Would not change. An email came in, I selected and then backed out and got the homescreen again. It hasn't happend again for me but my friend says it's been happening constantly and he's pulled his battery 6 times today. He's headed to V Store. If it happens again, that's a worrisome bug. Downloaded the new GVoice app and while it says "bug fixes" it's definitely slower and it's not refreshing as quickly. So I'd stay away from that if you haven't already downloaded.
Overal seems better but I'd like to know if other people are seeing the black screen issue.
