Is anyone else interested in how Google voice will affect calling minutes? If you currently have your GV number set to call your Sprint cell and your incoming call is from another cell phone will you be charged for the minutes? If you setup your phone so GV is used to call all numbers that you dial will you be charged for calling other cellular number because GV masks the number? I have been through every level of support that Sprint offers and no one can answer me. Sadly tier 3 technical support told me "Google Voice is useless on a cell phone and you would not want to use this anyway". I had nothing more to say after that! Anyone else have answers?
