I am always amazed by how late Verizon is to the OS update game. The latest release from Sprint brings OS 188.8.131.524 for the BlackBerry Tour 9630. This is the same version that was seeded out through desktop manager before but now it is available to download as an installer.
If you do not know how to upgrade your BlackBerry OS please start by reading this great step by step guide that Luis wrote up. NOTE: Don’t forget to delete the vendor.xml file located in c:program files>common files>research in motion>apploader to install it on a different carriers device.
Please confirm in the comments if this works for you!
