Welcome to
BlackBerryOS Ben-jammin!!!
My recommendation to you would be go with the .109. It is a very stable OS and runs very well. You can down load the OS
HERE.
Make sure you back up
Once downloaded double click the installer and intall to your pc
Once done installing it will ask if you want to launch the DM (NO)
now go to C:/ Program Files/ Common Files/ Research In Motion/ Apploader and delete the vendor.xml file
In the same folder is an icon, Loader.exe (looks like a phone) double click and follow the installation instructions (
make sure you back up)
