If you follow OS leak news, then chances are you already have this OS loaded and can move on about your business. However, if you're not as familiar with loading OS leaks or decided that the process of loading OS 10.3.1.2267 without the help of autoloaders was just too much hassle then this is the post for you.
If you head on into the CrackBerry Forums right now, you will find autoloaders for each device being uploaded, which only require you to download the typical one single file, run it and enjoy OS 10.3.1.2267 on your BlackBerry 10 smartphone.
No crazy patch files, no downloading of 3-4 different folders worth of apps along with separate downloads for the radio files, just a straight up good ol' autoloader. Q5, Q10 and Passport are already posted, the rest are on their way, you'll just have to wait a tad bit longer.
