One welcome new feature of Ice Cream Sandwich is the integrated
visual voicemail system, but Google isn't providing a built-in
app taking advantage of it. Visual voicemail is carrier
dependent, so ICS can only provide an API to let developers plug
into the system, meaning each network needs to develop an app
that works with its own service. Slashgear reached out to Google
and confirmed this is indeed the case, and the API should make
implementation a little simpler for carries and third parties.
So when the Galaxy Nexus launches on December 8th, there'll
probably be an app for that. If not, you know who to blame.
