With the help of BBLeaks, BlackBerry Curve 8530 owners now get the opportunity to upgrade their current operating system to a new leaked OS 5.0.0.886. Keep in mind if you are NOT having problems, then you shouldn’t update the OS. Every device acts different with software, so be sure and think about it before you update. Before installing the new OS to your BlackBerry Curve 8530, it is important that you backup all of your data to prevent any information from getting lost. The operating system is the platform of all programs, so installing the latest OS should enhance device  performance.
