We’ve been taking a more detailed look at what Nokia’s next-generation of smartphones have to offer in our Windows Phone Mango update in detail series, but two features we weren’t aware of before now are indoor maps and visual voicemail.

Windows Phone Mango in detail: what Nokia users have to look forward to

It’s no surprise that Mango’s full flavour has yet to emerge, of course: the update to Windows Phone 7 features upwards of 500 new features. So we can be sure there are plenty of juice details yet to emerge. As of now, however, we’re focusing on two specific highlights that have just emerged: indoor maps and visual voicemail.

Microsoft boss Steve Ballmer himself has revealed their existence, speaking at the company’s Worldwide Partner Conference in the US.

Nokia users probably need less introduction than most when it comes to indoor mapping. Back in April we got a glimpse of the Nokia High Accuracy Indoor Positioning system, and this certainly doesn’t look a million miles away - pardon the pun!

As for visual voicemail, it certainly looks interesting. Instead of your voicemails being at the end of the phone, as it were, they’re presented in list form in your Phone hub with a play button to the left of each, almost like a music playlist.

Each entry gives details of who the message is from and when it was left, the key info you need really. You can check out more details on these two new Windows Phone Mango features in the videos below. As with our in-depth articles on Mango, it’s PocketNow we have to thank for dishing up the details.
