Here’s a surprise. Nokia has added one of the most wanted features to Windows Phone through a simple Extras+info update on Lumia devices running on the Amber update. It was previously revealed that Microsoft had added hooks to its Windows Phone GDR2 release for developers to latch on, and those were of the call and SMS blocking features that didn’t exist before. While we were hoping for some third party developer to do it, Nokia itself has come to the fore and added these much requested features to Windows Phone, which is much welcome. Yet another indication that Nokia is doing the work for Microsoft when it should be the other way in an ideal world.
