Nexus One 3G problems persist after update -- is it a design problem?

Looks like someone at Google should fast forward those Nexus One design videos to the radio integration portion and figure out what went wrong, because it seems like the 3G coverage problem still hasn't been fixed, even after that last big OTA update. What's more, many in Google's support forums are noting that the phone will drop a weaker 3G signal merely when held by the bottom, as the video below clearly shows. Oops. We're not at all sure what's going on here, but we're hoping this issue can yet be solved with a software patch -- things are going to get messy if this is purely a hardware issue.
