I am coming from the Droid, and I am a bit confused as to how HTC sense manages contacts. I added my work email account, Facebook and gmail and now all my work contacts are showing up in my "people" phone book. I only want my Gmail contacts to show up... the same people I had on my droid.
:greendroid: I'm a newbie but I might be able to help here.
With your "People" app running, press menu.
Then select View (the eyeball)
You can then select which accounts you wish to display (Google, Verizon contacts, Facebook, etc). It's particularly helpful in that it can limit what you to those folks with phone numbers.
Hope that helps.
