    Hey everyone. I have a friend who has an 8800 and he wants to get bbm 5.0, but he only has OS 4.2.

    How can I help him upgrade to the latest 4.5 OS?

    Thanks!!

    Download the os software from this forum and delete the vender xml file. From there attach your blackberry to the computer and open desktop manager and it should prompt you from there. There are many many forums on doing this. Just search the site and you can get more detailed info also. Goodluck.
