I have a Blackberry 8310 from AT&T. It's running v22.214.171.124. I have a BES, running 126.96.36.199.
This morning, I downloaded Blackberry Desktop Manager 4.7, and installed it to my XP workstation. I then rebooted, as prompted.
I've also downloaded from AT&T, the 188.8.131.52 OS, and ran that executable.
According to other instructions here, I then went to C:\Program Files\Common Files\Research in Motion\AppLoader and got rid of Vendor.xml. I then connected my Blackberry while opening Desktop Manager. I selected Application Loader. At no point have I been prompted to Upgrade the OS, nor do I see any place to make this happen, and I am stumped on how to do this. Any help?
