I am now running 184.108.40.206 on my ESN 8330
Their is no file to download yet!
Seems you will need .131 installed on your BB and on your PC go to C:\Program Files\Common Files\Research In Motion\AppLoader and then for the vendor.XML file should be deleted or edit it to read <vendorsrc version="0.0.0.0">
Next (with your BB pluged into your PC but DM not running) go to www.balckberry.com/update
install the active X control and it will then launch your loader.exe app (it may update it to 220.127.116.11 first) and it should show you the 18.104.22.168 update.
I have confirmation form four people now and its not carrier specific.
