After using the new Sprint radio all day today, I can comfortably say that it isn't anywhere near as good as the Telus radio I was using. I've been dropping calls, receiving calls on the last ring before it redirects to VM (or missing them when they redirect before I can pick up) and generally getting very poor battery life (I'm sure this last one is because I'm only registering 0-2 bars in places I usually get 3 or more; It seems like I'm getting 2 less signal bars indicated across the board.)
Back to Telus... on my Sprint phone.
