If the latest rumour turns out to be true, you can add visual voicemail to the list of features coming to Windows Phone 7.5 (codename Mango). The rumour comes from Twitter account @WindowsPhone8 which had revealed a number of upcoming Windows Phone developer features ahead of Microsoft’s MIX11 conference.
The terse tweet (“#Wp7 Mango includes visual voicemail”) reveals little else.
Microsoft is expected to formally announce Windows Phone 7.5 at an upcoming event on March 24th.
