From Google Voice Blog: Google Voice Blog: Sprint integrates Google Voice. This is a terrific for Sprint customers. They will be able to use their Sprint number as their Google Voice number. The article goes into nice detail. I'm a Sprint customer, but this news doesn't benefit me as far as I can tell. I have Pick 3, a benefit that lets me make unlimited calls to and from 3 different numbers. Using my Google Voice as one of those numbers means my monthly allotted minutes aren't reduced by calls using Google Voice. I just hope that this won't cause problems for me. This Sprint/Google Voice relationship could put an end to my unlimited calls.
