The very first official OS 5.0 is now available for the BlackBerry Bold 9000 courtesy of Bell Mobility. RIM vaguely promised that you would be seeing OS 5 for older devices before 2010 and while they didn’t deliver in full, they have brought you the OS 5 for the Bold 9000 very early in the year. This build comes as OS 5.0.0.411 and is courtesy of Bell Mobility. Delete the vendor.xml file if you’re not with Bell.
