RIM vaguely promised that we would be seeing OS 5 for older devices before 2010 and while they didn’t deliver in full, they have at least brought us OS 5 for the Bold 9000 very early in the year. This build comes as OS 188.8.131.521 and is courtesy of Bell Mobility. Remember to delete the vendor.xml file if you’re not with Bell.
The vendor.xml file can be found in C:\Program Files\Common Files\Research In Motion\AppLoader.
