Re: Android, not yet. We're still working on an email to promote our iPhone app, and we want to see what sort of uptake we get on the app in general before we invest in a second platform.
Voice mail gets in my inbox as wav (mp3 would be nicer but wav is ok) so it's nice to have it in an app but not really necessary.
Being able to turn on or off call transfer simply (without having to use the web interface and authenticate) would be really nice.
