The antenna is on a plastic cover I dont know anything about how they work but it just seems like a dumb place to put a antenna and that it wouldn't work well.
The bars not updating issue happened on my Droid X once I upgraded to GB as well. I think I posted in one of these signal threads about it. I have used mobile signal widget for a long time because it is more accurate. Also any numbers I have posted in this thread are either from the network info or debug mode. I prefer to use debug mode as it updates the quickest.

Got my new 2 and was excited to be able to stream radio today but no signal all day, no mail, FB Web nothing, text and calls but nothing data related. Right now I am on my wifi and can do everything, I'm sure going to be pissed if this turns out to be no better than my old pay as you go virgin phone.
