It has been quite some time since we have seen a leak for the BlackBerry 9550. The last leaked OS was 126.96.36.1998 last year in December. To our surprise the 9550’s brother, the 9520, is already at OS 188.8.131.527! Could this be a sign that devices on many carriers are getting better support? Nevertheless, this build should hopefully be a good one, as it currently undergoes testing through Verizon.
