If you own a BlackBerry Tour and want to update to the latest “leaked” firmware, BlackBerry OS 4.7.1.53 is online and ready for download.
OS 4.7.1.53 for the BlackBerry Tour is not an official release and thus is not supported, so, if you decide to download it, get a good backup of your device before you implement it.
OS 4.7.1.53 can be found here…
