For those who HAVE received the update successfully, report all positives and negatives associated with it.
The only negative I have seen is the Madden 11 app. It is pretty gay and can't be uninstalled like you could the NFS Shift game when we got Froyo.
I haven't had the battery manager force close on me yet, so I guess they fixed that bug. I never had bug issues with the stock music player or Wi-fi so i can't speak to those. I also haven't gotten many texts yet to see if they fixed the bug which didn't always display the newest unread text on top, but that one didn't really plague my DX much either. It seems like a pretty smooth update so far, but again, I never had major issues with 2.2....just an occasional force close on the battery manager.
I really like the new dialer search feature that I mentioned above. That is pretty slick!
