It has been awhile since I was able to run App World on my Blackberry Bold, running 126.96.36.199 OS. All the previous versions of App World I tried would not run on .190 OS. My fellow writer Todd informed me yesterday that there was a COD file bundle for App World 188.8.131.52 available. I finally tried it today and voila it worked like a charm. Interestingly, the last version showing up on App World as a download was 184.108.40.206.
The zip file comes with 2 COD files and you can upload them to your device using Blackberry Swiss Army Knife application on your PC. Then reset your device and you are good to go.
