Windows Phone 8 is definitely picking up pace as a worthy alternative mobile operating system for those who have grown tired of iOS and Android, or who want to stay away from the mainstream offering. The firmware's cause is definitely helped by the growing number of quality apps that are appearing on the Windows Phone Store, some from large development houses and some from third-party indie developers. The platform may not have an official Instagram presence yet, but the innovative Instagram Lockscreen app that is now available could at least give Windows Phone 8 users a taste of what they are missing out on.
