I've been using the Bold for 6 days.  There is definitely a signal problem.  I've held it next to my old 8330 and there is a signal drop to the Bold.  I had an email problem and couldn't get through to VZW customer service; eventually did and got escalated to tech support who bumped me to RIM tech support - who were surprisingly uninformed and unhelpful.  I'm still going to stick with this phone, but...  I'd like some improvements.
