Yesterday, I found 10.3.x OS is available for my device but due to lack of wifi I could not update. But, now, when I am trying to get my BlackBerry z3 updated to OS 10.3.X., it is showing that my current OS 10.2.X is latest for my device.
If you want to update your Z3 you are going to have to download it yourself. Here is the link.http://forums.crackberry.com/bb10-le...oaders-995995/
Download the file you need, unzip it and run the autoloader. It will wipe your phone and install the new OS. If you have made a backup first you can restore some of your information.
