OS 6.0.0.359
Turkish carrier AVEA has made OS 6.0.0.359 official for the BlackBerry Bold 9780 which is the same version that was leaked last month. If you want to load this up on your Bold 9780 remember to delete your vendor.xml if you are not an AVEA customer.
It is always recommended that you backup your phones data with the BlackBerry Desktop Software before installing a new operating system.
