EASYRHIN0 Great app! Works well with Growl->Prowl notifications. It would be nice if you could consolidate contact numbers under one entry.
Skype for OSX splits the contacts from address book in the same way, so perhaps it's a limitation with Address Book/OSX. Pulling contacts from Address Book seems to work better than from Google Voice. When pulling the contacts from Google Voice I end up with a bunch of strange entries from old mobile phone# that have long been deleted from my google contacts. It will just show the old number as an entry with no name.
