And the unofficial BlackBerry smartphone operating systems still keep popping up on the internet, this one is from ietehun over @BBHybrids who according to berryreview, has posted OS 5.0.0.287 for the BlackBerry Storm 2 9550.
Obviously this OS 5.0.0.287 is a leaked version so the following disclaimer applies…should you install this OS on your BlackBerry Storm 2 9550 you do so at your own risk.
Or you could simply just be patient and grab the official OS 5.0 for the BlackBerry Storm 2 9550 when it hits. In any case make sure you know what you are doing or your smartphone may end up a brick.
