My iPhone cleverly switches to WiFi without me even knowing. But why can't the 3G radio turn off at this point to save battery? Is there a way to do this automatically besides having to manually shut it off? Thanks!
I think it's really great that it does this - not only is the speed better, but if 3G is switched off in the process, battery won't drain as much.
