I know GV does not support 3 way calling. So today I called my father via GV International calling. I needed to add a call. I went into my phone, which is the HTC Incredible, and hit +ADD CALL. I hit another contact and it went to Connecting page. After about 5 seconds it says: Retry with google voice or Retry without google voice I hit "WITHOUGH GOOGLE VOICE" The call conncected and I'm still talking three way at the moment. Are there going to be any extra charges from either Verizon or my Google Voice account?
