If you are packing a BlackBerry Storm 9520 smartphone and fancy an operating system update, then you may like to know that an unofficial OS 5.0.0.436 update is available to the BlackBerry Storm 9520 reports an article over on crackberry.

Unfortunately any detailed information as to what OS 5.0.0.436 brings is scant so if you do happen to download it to your BlackBerry Storm 9520 fell free to let us know if there are any major changes.

Of course as this OS 5.0.0.436 update to the BlackBerry Storm 9520 is unofficial the usual disclaimer applies and you download and install the update at your own risk, so please make sure you backup your data before doing so.

Other than that there’s no more to say except go grab OS 5.0.0.436 for your BlackBerry Storm 9520 handset if you want it, or you can simply hang on for an official update which will no doubt come eventually.
