We finally managed to install Windows 10 for Phones preview Build 10051 on our Lumia 525. The build brings the same OS version 10.0 12534.56 that was claimed in rumors. Time to have a look at some of the screenshots that give a good idea into what the build brings, though stay tuned for our hands-on coverage.
