Ok so now that it's out there I will give my input.
Been using it since 10/2 and find signal strength 2G/3G/Wifi to all be improved. I still have some concerns about battery life, regular network use is fine, 2G/3G/Wifi are fine but using media player seems to be a big power hog and maybe it's as good as it will get....
For those that have problems I implore you to consider that there are HW changes that have come out in the course of at&t's testing and Orange in the UK recently suspended shipping on Bolds until RIM resolved the issue. Point is the SW may be fine but you may be loading it on old HW...
