You are not forwarding your cell number, you are simply forwarding the no answer transfer *28 for your Vmail service, I simply use GV for dialing International calls to Canada, for free, of course that I use my cell minutes
Since were talking Google Voice a bit... When you forward to your GV number don't you lose your free cell to cell minutes? My understanding is that all GV connections are ground lines so they will count against your limited minutes. This is really the only thing holding me back from moving to GV
