1) Install Blackberry Desktop Manager if you have not installed one
2) Download the leaked OS (http://www.multiupload.com/G4MHWLAMWB)
3) Run the leaked OS installer once downloaded
4) Find the vendor.xml file under the following locations and delete it
a) "C:\Users\<UserID>\AppData\Roaming\Research In Motion\BlackBerry\Loader XML\"
b) "C:\Program Files(X86)\Common Files\Research In Motion\Apploader\"
5) Connect your Blackberry using USB cable
6) Start Desktop manager and it should prompt you for an upgrade available.
Another thing I noticed is that at the top of my Messages folder, there's a stand-alone message under the label (where a date usually is) "BlackBerry: Important." The message is from BlackBerry and says "Action Required: Activate Email." It asks me to "click Activate Email" so I can "associate [my] BlackBerry ID with [my] email service."
If I click on Activate Email, I have a list of my email accounts awaiting the input of my passwords for each one. I haven't done this (yet) -- not sure why I want to associate all of my email accounts with my BlackBerry ID. I already have one associated with it, and why do they want the password to that email account anyway, when I have a separate password for BlackBerry ID?
