Got my Incredible yesterday. At home in my office, I barely get a connection. It ranges from no bars to 1. the 3G icon is not lit. I also have a home wireless G network and it seems to be beyond that range too, although my laptop picks it up.
Sitting here with my Wife's Moto Droid side by side with my Incredible. Hers has 3 to 4 bars and the 3G indicator lit. Mine has 0-1 ,and no 3G.
