Yesterday a new BlackBerry Z10 OS leak was introduced to the masses OS 10.1.0.1429. Having done hybrid and leaked OS builds since my first BlackBerry (the Storm), I have jumped at every chance to try a new build, and this was no different. My device is on the Verizon network, and as such I had already loaded the 10.0.10.822 on prior to this leak, so I knew through some trial and error already how to load this leak. Give yourself about 2 hours to do this, and I think you will find that after the OS settles, it truly is a solid build. I will not go into the process of downloading the OS here as there are plenty of resources out there to help you with that. However, I am going to give you my initial feedback on the OS and in my opinion, what I find to be the best and maybe even worst (gasp!) of the build.
