What's truly amazing though, is that there hasn't been a 3rd party app that provides this functionality ever since WP7 and its offspring have been kicking-in Andriod I got tons of thrid-party options for this issue. Even worse-Windows Mobile had apps that did this before they put that platform out to pasture and went down the Windows Phone path.
Add on top of that the addition of Interop Unlock and you are looking at a developer-hostile platform on the level of iOS-except WP8 is no iOS.
Unless the next few Blue updates correct these kinds of deficiencies, I don't see Windows Phone surviving by the start of 2015. Microsoft needs to be reminded that Windows Phone is a Phone-neutering jail that from a feature standpoint even the late lamented Symbian phones had just totally makes WP look like a shiny toy; rather than a serious phone workhorse-after all these things ARE phones at the end of day-take away voice and SMS support and they're nothing but small tablets.
To think that my lowly Nokia N900 does some things that Windows Phone can only dream of ought to make someone go slap Elop and his predecessors upside the head and realize that Maemo and its recent descendents (Meego on the N9, Jolla) actually worked and was a suitable platform to build upon, rather than roll the Redmond dice-especially since WP has other HW vendors in the mix and itsn't exclusive to Nokia-hell, even Nokia's been releasing some of their crown jewels to everyone-WTF?
